Qualitative description of image formed in mirror and lens.pptx
This document discusses the reflection of light in mirrors and the formation of images. It defines key terms related to reflection such as incident ray, reflected ray, normal line, and angle of incidence and reflection. It describes the two types of mirrors - plane and curved - and explains that plane mirrors form virtual images that are the same size and behind the mirror. Curved mirrors can form real or virtual images, depending on if the object is between the focus and center of curvature or beyond the focus. The document also discusses image characteristics such as location, orientation, size and type.
Uses-of-Mirrors-and-Lenses.pptx
this presentation will hepl you in studying and reviewing to cope up with your lessons. Because mirrors reflect light, they create an illusion of open space by doubling whatever is in a room. Interior decorators use mirrors to make rooms feel larger and more inviting than they truly may be. Certain styles of mirrors may give a room a certain atmosphere based on their appearance. Additionally, decorators may use lenses to reflect light or add color. They may place candles on mirrors to magnify the shimmering effect or use a series of prisms to create rainbows in a white room.

Fault (Science 8)
This document discusses different types of faults in the Earth's crust. It describes dip-slip faults as occurring at an angle of 45-65 degrees with the surface, including normal faults where the hanging wall moves down and reverse faults where the hanging wall moves up. Strike-slip faults involve lateral movement along the fault line in either a left-lateral or right-lateral direction. Oblique faults combine dip-slip and strike-slip movement. Active faults are those which have moved within the last 10,000 years and are likely to produce future earthquakes.
Reflection and Mirrors
Light is an electromagnetic wave that can be reflected, absorbed, or refracted. The law of reflection states that the angle of incidence equals the angle of reflection. Mirrors can form either real or virtual images. Concave mirrors focus parallel light rays to a focal point, forming real, inverted, and reduced images between the focal point and center of curvature. The mirror equation and magnification equation can be used to calculate the location and characteristics of an image formed by a spherical mirror.

3. Grade-7-SLM-Q2-Module-2-Levels-of-Biological-Organization-2nd-Ed.pdf
The document provides information about different levels of biological organization from cells to the biosphere. It discusses that cells make up tissues, tissues make up organs, organs make up organ systems, and organ systems along with organisms make up populations and ecosystems. The highest level of organization is the biosphere, which includes all living and nonliving things on Earth.
The microscope grade 7
The document summarizes the history and components of microscopes. It explains that while simple microscopes date back thousands of years, the compound microscope was developed in the late 16th century by Hans Janssen and Zacharias Janssen in Holland. Major improvements were made by Anthony van Leeuwenhoek and Robert Hooke. The document then describes the basic parts of a microscope including the objective lenses, ocular lens, stage, light source, and how magnification is calculated. It concludes with brief descriptions of other types of microscopes such as fluorescence, pocket, and dissecting microscopes.
concave mirror activity sheet
This document outlines an experiment to construct ray diagrams and describe images formed by a concave mirror as the object position is varied. The experiment involves placing an object at different positions (at C, at F, beyond C, between F and C, between F and V, and between F and C) and drawing the corresponding ray diagram to determine the image position, size, orientation, and type (real or virtual). The document then asks the student to analyze how the image changes as the object position varies and to discuss the importance of concave mirrors and examples of devices that use them.
Comets, asteroids & meteors
Comets and asteroids are remnants from the formation of the solar system. Comets originate from the Kuiper Belt and Oort Cloud and are icy bodies, while asteroids originate from the Main Asteroid Belt and are rocky fragments. Both have irregular shapes and sizes ranging from 1-100 km. Comets have highly elliptical orbits with periods of 75 years to millions of years, while asteroids have more rounded orbits with periods of 1-100 years. When a meteoroid from space enters the atmosphere, it becomes a meteor or "shooting star"; any fragments that reach the ground are called meteorites.
2.1 2.2 epicenter and focus and magnitude and intensity.pptx
The focus is the point where rock breaks during an earthquake and seismic waves begin, which can be at deep or shallow depths. The epicenter is the point on the surface directly above the focus and is usually what is used to locate the position of an earthquake. Magnitude measures the strength of energy released during an earthquake using the Richter scale, while intensity measures the damage or effects based on the Mercalli or PEIS scales.
Mirrors ppt
This document discusses different types of mirrors and how they work. It explains that convex mirrors produce smaller, virtual images behind the mirror, while concave mirrors can produce either magnified real images or virtual images, depending on the object's distance from the mirror. The document also introduces ray diagrams as a tool to determine image characteristics like location, size, and whether the image is real or virtual.

1) Identifying the main parts of the microscope and their functions, such as the eyepiece for magnification and the objectives for further magnification.
2) Describing techniques for focusing a microscope, such as using the coarse adjustment knob to move the body tube and fine adjustment knob for finer focus.
3) Explaining how to calculate magnification by multiplying the eyepiece magnification by the objective magnification, such as getting 100x magnification using a 10x eyepiece and 10x objective.
Earthquakes and Fault Grade 8
Earthquakes occur along fault lines where the earth's crust has cracked, forming weak spots. There are two main types of earthquakes - tectonic earthquakes caused by movement of tectonic plates, and volcanic earthquakes caused by volcanic activity. Faults are classified based on the movement under the crust, such as dip-slip, strike-slip, and oblique-slip faults. Active faults are those likely to produce future earthquakes, as movement has occurred within the past 10,000 years, such as the Philippine West Valley Fault Line and Philippine Fault.
QUARTER 2-LESSON 1.pptx
This document provides an overview of different forms of electromagnetic waves. It begins with learning objectives related to comparing wavelengths, frequencies, and the relationship between wavelength, frequency, and energy of EM waves. It then reviews key wave terms like amplitude, wavelength, and frequency. Learners are asked to recreate waves using a rope to observe how wavelength and amplitude change with hand speed. The document defines electromagnetic waves as waves from oscillating electric and magnetic fields that can travel through vacuum. It reviews Oersted's and Faraday's discoveries relating electric and magnetic fields. Finally, it introduces the electromagnetic spectrum and frequency ranges of different EM wave types.
Introduction to light
1. In the 17th century, Isaac Newton and Christian Huygens proposed different theories on the nature of light - Newton believed light consisted of particles while Huygens believed it was a wave.
2. Through experiments like the double slit experiment, it was shown that light exhibits both wave-like and particle-like properties.
3. Modern understanding is that light has a dual nature, it can behave as a particle called a photon as well as a wave. This is called the wave-particle duality of light.
Third Grading Module 4 Light
Light can behave as both a particle and wave. It is an electromagnetic wave that is visible to the human eye and is responsible for sight. Several scientists throughout history studied the nature of light, including Isaac Newton who believed it behaved as particles, Christian Huygens who believed it behaved as waves, and Max Planck who proposed light has both wave-like and particle-like properties. James Clerk Maxwell later unified concepts of light, electricity, and magnetism in his electromagnetic theory of light.
SCIENCE7: Asexual and Sexual Reproduction
This document discusses asexual and sexual reproduction. It begins by defining the two types of reproduction and their key differences. Asexual reproduction involves one parent and produces genetically identical offspring, while sexual reproduction involves two parents and produces offspring with genetic variation. The document then explains various types of asexual reproduction, including binary fission, budding, regeneration, and vegetative propagation. It also covers the process of sexual reproduction, including fertilization. Key differences between asexual and sexual reproduction are outlined such as number of parents involved, genetic makeup of offspring, use of gametes, and relative rates of reproduction. Students are then given questions to test their understanding of the concepts.
Biological levels of organization for Grade 7
The document discusses the levels of organization in biology from the smallest to largest. It begins with cells, which are the basic unit of life, and discusses tissues, organs, organ systems, organisms, populations, ecosystems, and finally the biosphere. Key characteristics of life are also defined, including being composed of cells, reproduction, growth and development, obtaining and using energy through metabolism, responding to the environment through homeostasis, having DNA as the universal genetic code, and evolving through adaptation.
Generator vs motor electromagnetism
This document discusses electricity and magnetism for a 10th grade science class. It explains that electricity can be generated by changing magnetic fields near a conductor through electromagnetic induction. A simple electric motor converts electrical energy to mechanical energy, while a simple generator converts mechanical energy to electrical energy. Students will assemble both a simple electric motor and generator and explore real-life applications of these devices.
Heat (grade 8)
“HEAT”
Heat is a form of energy that flows from warmer bodies to colder bodies.
It is viewed as a form of energy that is transferred from one body to another due to a difference in temperature.
The SI unit of heat is joule (J).
Common unit of heat is calorie.
CALORIE the amount of heat needed to change the temperature of one gram of water from the pressure of the atmosphere.
TEMPERATURE

Light and Color
Light is electromagnetic radiation that can behave as both a particle (photon) and a wave. It travels at 300 million meters per second in a vacuum. When light interacts with matter, it can be transmitted, reflected, scattered, absorbed, or refracted. The color of light depends on its wavelength, with shorter wavelengths like blue having higher frequencies and energies than longer wavelengths like red.
Relationship between fault and earthquake
This document contains information about a lesson on earthquakes. It includes objectives, standards, and activities about earthquakes and faults. The lesson will have students use models to explain how movement along faults generates earthquakes. It will also have them differentiate between the epicenter and focus of an earthquake. Activities include creating a model of the layers of the Earth, an inquiry lab involving sand and styrofoam to show what parts of Earth experience earthquakes, and a discussion of different types of faults.
Quarter 1,module 3.pptx
Active volcanoes, earthquake epicenters, and major mountain belts are mostly found along plate boundaries. As the plates move, geological events occur where the plates meet. Most volcanoes are located along boundaries like the Ring of Fire in the Pacific Ocean. Earthquake epicenters are also commonly found near plate boundaries where tectonic plates collide, diverge, or move past each other. Likewise, major mountain ranges tend to form at plate boundaries due to compression as the plates converge. The distribution of these geological features relates to plate tectonic theory, which explains that their formation is caused by the movement and interactions of tectonic plates.
reflection in curved mirror.ppt
The document provides guidance on safety practices during the COVID-19 pandemic, including maintaining physical distance, good hygiene, wearing face masks and limiting exposure. It also discusses the properties of concave mirrors and how light rays behave when reflecting off of one. Key points covered include that concave mirrors can form real or virtual images that are upright or inverted, and can be magnified, minified or the same size as the object. Ray diagrams are demonstrated as a way to determine the characteristics of an image formed by a concave mirror.
Spherical mirror by Kshitiz Rai
This document discusses virtual and real images formed by mirrors. Virtual images cannot be projected onto a screen and are always on the opposite side of the mirror from the object. Real images can be projected onto a screen and are on the same side of the mirror as the object. Concave mirrors form real, inverted images between the focal point and center of curvature for objects beyond the center of curvature. Ray diagrams are used to determine the nature and position of images formed by concave mirrors depending on the object's position relative to the focal point and center of curvature. The mirror equation can also be used to calculate the position of images.

Concave mirrors produce real or virtual images depending on the position of the object, while convex mirrors only produce virtual images. Lenses can be either converging or diverging. Converging lenses are thicker in the middle and can form real or virtual images, while diverging lenses are thicker on the edges and always form virtual images.
Lenses 1
There are two main types of lenses: convex and concave. Convex lenses converge parallel light rays and form a real, inverted, and diminished image at a focal point. Concave lenses diverge parallel light rays and form a virtual, upright, and smaller image. The document provides diagrams and examples to illustrate how light rays behave when passing through different lenses, including how to measure a lens's focal length. It also discusses the formation of real images using convex lenses in cameras and magnified virtual images using concave lenses in projectors.
Module 4 optical instruments
This module discusses optical instruments. It covers the human eye, cameras, microscopes, telescopes, and holograms. The human eye and camera form small, inverted, real images on the retina and film, respectively. Microscopes use two lenses to magnify small objects, forming an enlarged final image for viewing. Telescopes similarly use two lenses to make distant objects appear larger. The module aims to explain how these optical devices work and form images.
Light
This document provides a summary of key concepts about light, reflection, mirrors, lenses, and rainbows. It defines light and explains that it travels in straight lines and can be reflected or absorbed when hitting objects. Reflection is defined as light changing its path when hitting a surface. Plane and curved mirrors are described, as are the formation of real and virtual images. The properties of convex and concave lenses and mirrors are outlined, including the types of images they form. Rainbows are explained as occurring due to the refraction of sunlight through water droplets, separating white light into the visible color spectrum.
Light Lesson 2
The document discusses the properties of images formed by plane mirrors. It notes that the angle of incidence of light hitting a plane mirror is equal to the angle of reflection. There are two types of mirrors: flat mirrors and curved mirrors, with flat mirrors also being called plane mirrors. The key facts provided about images formed in plane mirrors are that they are erect, virtual, form as far behind the mirror as the object is in front of it, and are laterally inverted.
WK2-MIRROR-FINAL.pptx
This document discusses the qualitative characteristics of images formed by plane and curved mirrors and lenses. It begins by stating the objectives of predicting the orientation, type, and magnification of images formed, and explaining the uses of lenses and mirrors. It then provides information on the reflection of light in plane and curved mirrors, including definitions, laws of reflection, and the characteristics of images formed. It also discusses the two types of spherical mirrors - concave and convex - and their uses. Finally, it outlines the uses of convex and concave lenses, including in microscopes, cameras, correcting vision, and as the natural lenses in human eyes.
U10 Cn2 Lens Intro
This document provides an introduction to converging and diverging lenses. It discusses how converging lenses bring parallel rays of light together at a focus, while diverging lenses spread them apart as if from a focus. Convex lenses are generally converging, while concave lenses are generally diverging. Lenses can form real or virtual images. Real images can be projected on a screen, while virtual images cannot. The document also outlines the ray tracing rules for determining the path of light through converging and diverging lenses.
Chapter 10 introduction lenses
This document discusses lenses and their properties. It defines convex and concave lenses, and explains that convex lenses converge light rays while concave lenses diverge them. It then describes the six cases of image formation by a convex lens depending on the object's position, including real/virtual and inverted/upright properties. Sign conventions for thin lens equations are also provided. The document contains questions related to identifying lens types, drawing ray diagrams, and calculating thin lens image characteristics.
Thin lenses
This document discusses thin lenses and their uses. It compares converging and diverging lenses, and how they are used in eyeglasses to correct nearsightedness and farsightedness. Compound microscopes and telescopes use multiple lenses - microscopes have objective and ocular lenses, while telescopes have objective and eyepiece lenses. Eyeglasses hold lenses in a frame to correct vision, while contact lenses are worn directly on the eye.
spherical lens.pptx
This document discusses different types of lenses, including convex and concave lenses. A convex lens is thicker at the center and thinner at the edges, forming an image that is real, inverted, and appears close to the lens. A concave lens is thicker at the edges and thinner at the center, forming an image that is virtual, erect, and appears far away. Examples of applications of convex and concave lenses include spectacles, telescopes, binoculars, flashlights, and spy holes. The document asks questions to test understanding of lens properties and applications.
QUIZ NO 5.pptx
This document contains a quiz with questions to identify whether statements pertain to virtual images or real images. It also contains questions to identify types of mirrors based on descriptions of how they reflect light rays. The quiz tests knowledge of image formation by plane mirrors, concave mirrors, and convex mirrors, and the meaning of the abbreviation S.A.L.T.

Compositions of iron-meteorite parent bodies constrainthe structure of the pr...
Magmatic iron-meteorite parent bodies are the earliest planetesimals in the Solar System,and they preserve information about conditions and planet-forming processes in thesolar nebula. In this study, we include comprehensive elemental compositions andfractional-crystallization modeling for iron meteorites from the cores of five differenti-ated asteroids from the inner Solar System. Together with previous results of metalliccores from the outer Solar System, we conclude that asteroidal cores from the outerSolar System have smaller sizes, elevated siderophile-element abundances, and simplercrystallization processes than those from the inner Solar System. These differences arerelated to the formation locations of the parent asteroids because the solar protoplane-tary disk varied in redox conditions, elemental distributions, and dynamics at differentheliocentric distances. Using highly siderophile-element data from iron meteorites, wereconstruct the distribution of calcium-aluminum-rich inclusions (CAIs) across theprotoplanetary disk within the first million years of Solar-System history. CAIs, the firstsolids to condense in the Solar System, formed close to the Sun. They were, however,concentrated within the outer disk and depleted within the inner disk. Future modelsof the structure and evolution of the protoplanetary disk should account for this dis-tribution pattern of CAIs.

Evidence of Jet Activity from the Secondary Black Hole in the OJ 287 Binary S...
Wereport the study of a huge optical intraday flare on 2021 November 12 at 2 a.m. UT in the blazar OJ287. In the binary black hole model, it is associated with an impact of the secondary black hole on the accretion disk of the primary. Our multifrequency observing campaign was set up to search for such a signature of the impact based on a prediction made 8 yr earlier. The first I-band results of the flare have already been reported by Kishore et al. (2024). Here we combine these data with our monitoring in the R-band. There is a big change in the R–I spectral index by 1.0 ±0.1 between the normal background and the flare, suggesting a new component of radiation. The polarization variation during the rise of the flare suggests the same. The limits on the source size place it most reasonably in the jet of the secondary BH. We then ask why we have not seen this phenomenon before. We show that OJ287 was never before observed with sufficient sensitivity on the night when the flare should have happened according to the binary model. We also study the probability that this flare is just an oversized example of intraday variability using the Krakow data set of intense monitoring between 2015 and 2023. We find that the occurrence of a flare of this size and rapidity is unlikely. In machine-readable Tables 1 and 2, we give the full orbit-linked historical light curve of OJ287 as well as the dense monitoring sample of Krakow.
Signatures of wave erosion in Titan’s coasts
The shorelines of Titan’s hydrocarbon seas trace flooded erosional landforms such as river valleys; however, it isunclear whether coastal erosion has subsequently altered these shorelines. Spacecraft observations and theo-retical models suggest that wind may cause waves to form on Titan’s seas, potentially driving coastal erosion,but the observational evidence of waves is indirect, and the processes affecting shoreline evolution on Titanremain unknown. No widely accepted framework exists for using shoreline morphology to quantitatively dis-cern coastal erosion mechanisms, even on Earth, where the dominant mechanisms are known. We combinelandscape evolution models with measurements of shoreline shape on Earth to characterize how differentcoastal erosion mechanisms affect shoreline morphology. Applying this framework to Titan, we find that theshorelines of Titan’s seas are most consistent with flooded landscapes that subsequently have been eroded bywaves, rather than a uniform erosional process or no coastal erosion, particularly if wave growth saturates atfetch lengths of tens of kilometers.
Candidate young stellar objects in the S-cluster: Kinematic analysis of a sub...
Context. The observation of several L-band emission sources in the S cluster has led to a rich discussion of their nature. However, a definitive answer to the classification of the dusty objects requires an explanation for the detection of compact Doppler-shifted Brγ emission. The ionized hydrogen in combination with the observation of mid-infrared L-band continuum emission suggests that most of these sources are embedded in a dusty envelope. These embedded sources are part of the S-cluster, and their relationship to the S-stars is still under debate. To date, the question of the origin of these two populations has been vague, although all explanations favor migration processes for the individual cluster members. Aims. This work revisits the S-cluster and its dusty members orbiting the supermassive black hole SgrA* on bound Keplerian orbits from a kinematic perspective. The aim is to explore the Keplerian parameters for patterns that might imply a nonrandom distribution of the sample. Additionally, various analytical aspects are considered to address the nature of the dusty sources. Methods. Based on the photometric analysis, we estimated the individual H−K and K−L colors for the source sample and compared the results to known cluster members. The classification revealed a noticeable contrast between the S-stars and the dusty sources. To fit the flux-density distribution, we utilized the radiative transfer code HYPERION and implemented a young stellar object Class I model. We obtained the position angle from the Keplerian fit results; additionally, we analyzed the distribution of the inclinations and the longitudes of the ascending node. Results. The colors of the dusty sources suggest a stellar nature consistent with the spectral energy distribution in the near and midinfrared domains. Furthermore, the evaporation timescales of dusty and gaseous clumps in the vicinity of SgrA* are much shorter ( 2yr) than the epochs covered by the observations (≈15yr). In addition to the strong evidence for the stellar classification of the D-sources, we also find a clear disk-like pattern following the arrangements of S-stars proposed in the literature. Furthermore, we find a global intrinsic inclination for all dusty sources of 60 ± 20◦, implying a common formation process. Conclusions. The pattern of the dusty sources manifested in the distribution of the position angles, inclinations, and longitudes of the ascending node strongly suggests two different scenarios: the main-sequence stars and the dusty stellar S-cluster sources share a common formation history or migrated with a similar formation channel in the vicinity of SgrA*. Alternatively, the gravitational influence of SgrA* in combination with a massive perturber, such as a putative intermediate mass black hole in the IRS 13 cluster, forces the dusty objects and S-stars to follow a particular orbital arrangement.

Microbial interaction
Microorganisms interacts with each other and can be physically associated with another organisms in a variety of ways.
One organism can be located on the surface of another organism as an ectobiont or located within another organism as endobiont.
Microbial interaction may be positive such as mutualism, proto-cooperation, commensalism or may be negative such as parasitism, predation or competition
Types of microbial interaction
Positive interaction: mutualism, proto-cooperation, commensalism
Negative interaction: Ammensalism (antagonism), parasitism, predation, competition
I. Mutualism:
It is defined as the relationship in which each organism in interaction gets benefits from association. It is an obligatory relationship in which mutualist and host are metabolically dependent on each other.
Mutualistic relationship is very specific where one member of association cannot be replaced by another species.
Mutualism require close physical contact between interacting organisms.
Relationship of mutualism allows organisms to exist in habitat that could not occupied by either species alone.
Mutualistic relationship between organisms allows them to act as a single organism.
Examples of mutualism:
i. Lichens:
Lichens are excellent example of mutualism.
They are the association of specific fungi and certain genus of algae. In lichen, fungal partner is called mycobiont and algal partner is called
II. Syntrophism:
It is an association in which the growth of one organism either depends on or improved by the substrate provided by another organism.
In syntrophism both organism in association gets benefits.
Compound A
Utilized by population 1
Compound B
Utilized by population 2
Compound C
utilized by both Population 1+2
Products
In this theoretical example of syntrophism, population 1 is able to utilize and metabolize compound A, forming compound B but cannot metabolize beyond compound B without co-operation of population 2. Population 2is unable to utilize compound A but it can metabolize compound B forming compound C. Then both population 1 and 2 are able to carry out metabolic reaction which leads to formation of end product that neither population could produce alone.
Examples of syntrophism:
i. Methanogenic ecosystem in sludge digester
Methane produced by methanogenic bacteria depends upon interspecies hydrogen transfer by other fermentative bacteria.
Anaerobic fermentative bacteria generate CO2 and H2 utilizing carbohydrates which is then utilized by methanogenic bacteria (Methanobacter) to produce methane.
ii. Lactobacillus arobinosus and Enterococcus faecalis:
In the minimal media, Lactobacillus arobinosus and Enterococcus faecalis are able to grow together but not alone.
The synergistic relationship between E. faecalis and L. arobinosus occurs in which E. faecalis require folic acid
