Ch 25 Light Reflection: Mirrors
The document summarizes key concepts about the reflection of light by plane and spherical mirrors, including:
1) Plane mirrors form virtual, upright images that are the same size as the object and located the same distance behind the mirror as the object is in front of it.
2) Spherical mirrors can form real or virtual images, depending on whether the mirror is convex or concave. Concave mirrors always form virtual images while convex mirrors form real images.
3) Ray diagrams can be used to locate the image position by tracing the path of light rays reflecting off the mirror according to the law of reflection.
Unit 28 - Heat And Temperature
Temperature is a measure of the average kinetic energy of particles, with higher temperatures indicating faster particle motion. There are three main temperature scales: Fahrenheit, Celsius, and Kelvin. Fahrenheit and Celsius are used to measure temperatures experienced in daily life, while Kelvin is used for scientific purposes since it does not have negative values. Heat is transferred between objects through conduction, convection, and radiation. Conduction requires direct contact, convection occurs through fluid movement, and radiation transfers heat via electromagnetic waves.

1. Earthquake and Faults
Convection currents in the earth's mantle cause the movement of tectonic plates. Faults form at the boundaries of these plates where the rocks are weak. When stress builds up along fault lines from the movement of plates, it causes the faults to slip suddenly and generate earthquakes. There are three main types of faults - normal, reverse, and strike-slip - which move in different ways due to tensional, compressional, or shear stresses. Active faults have generated earthquakes within the last 10,000 years and may continue to do so, while inactive faults have not produced quakes recently but could still be capable of generating future seismic activity.

slm on Refraction class 8th
Refraction is the bending of light when passing from one medium to another. It occurs because the speed of light decreases in denser mediums. This causes light rays to bend when crossing boundaries between different transparent materials. Snell's law describes the relationship between the angles of incidence and refraction. Total internal reflection occurs when light travels from a denser to rarer medium at an angle above the critical angle, causing the light to be totally reflected at the boundary rather than refracted. A prism uses refraction to disperse white light into a spectrum of colors due to different wavelengths bending by different amounts.
Refraction of light
This document discusses refraction of light and how it causes bending of light rays when passing from one transparent medium to another. It introduces examples of refraction like objects appearing raised, distorted, or in different positions than they actually are. It then explains that refraction occurs due to a change in light speed between different densities of medium, causing the light to bend toward or away from the normal. Finally, it presents Snell's law which states that the ratio of sines of the angle of incidence and refraction is a constant called the refractive index.

5.2 refraction of light
- Light rays change direction when passing from one medium to another with a different density, known as refraction.
- Snell's law states that the ratio of sine of the angle of incidence to the sine of the angle of refraction is a constant equal to the refractive index.
- The refractive index is a ratio of the speed of light in a vacuum to the speed of light in a medium, and determines how much light will bend. Materials with a higher refractive index have a greater bending effect.
Light
This document provides an overview of the grade 11 physical science topic of light, including geometrical optics. It discusses the nature of light, reflection of light, refraction of light, and lenses. Reflection is defined as the bouncing of light off a surface, while refraction is the bending of light when passing from one medium to another. Examples of refraction include light bending as it passes from air to water. Lenses are able to refract light in a way that converges or diverges the beams, with converging lenses bringing light to a focus and diverging lenses spreading it out. Diagrams are provided to illustrate reflection, refraction, and the use of lenses to form images.
6.4 bending light
The document discusses the refraction of light and how it causes optical illusions. It explains that when light travels from one material to another of different density, it changes direction.

The document provides instructions for an experiment to observe and measure the refraction of light through a glass block at different angles of incidence.
Refraction of light law of refraction - class 10
Class 10 science - Light travels in a straight line until it hits something else. However, when light travels from one transparent medium and hits another transparent medium, the existing ray of light bends at a different angle from the second transparent medium. This bending of light from one medium to another medium is called refraction.

The refractive index is defined as the ratio of the speed of light in a vacuum to the speed of light in a medium. Examples of refraction in everyday life are given, as well as the history and uses of the refractive index. An experiment is described to measure the angles of incidence, refraction, and emergence using a glass slab.

Refraction of light
Refraction of Light occurs when light passes from one medium to another at an angle and changes speed, causing it to bend. The document discusses how refraction allows situations like fish appearing larger in water, spoons appearing bent in glasses, and rainbows forming. Examples are provided of materials like glass, water, and diamonds that light can pass through at different speeds. Diagrams demonstrate how the direction of light changes when going from one medium to another due to refraction.
Refraction of light 1
This document discusses the concept of refraction of light. It defines refraction as the bending of light when passing from one medium to another of different density, causing the light's speed and wavelength to change. The direction light bends depends on whether it is moving to a less or more dense medium. Snell's Law quantifies the relationship between the angles of incidence and refraction using the indices of refraction of the media. The index of refraction varies between substances and is related to the speed of light in that medium.

The direction light bends depends on whether it is moving to a less or more dense medium. Snell's Law quantifies the relationship between the angles of incidence and refraction using the indices of refraction of the media. Examples are provided to illustrate how refraction causes objects to appear in different positions than their true locations when viewed through materials like water or lenses.
Refraction
Refraction is the bending of light waves that occurs when light travels from one medium to another with a different density, such as from air to water. The document explains that refraction is caused by a change in the speed of light, with waves traveling slower in denser mediums, which causes the wavelength to reduce and the frequency to remain unchanged. Snell's law is also described, which quantifies the relationship between the angles of incidence and refraction based on the refractive indices of the two mediums.

The document provides a summary of key optical concepts discussed in a lecture on numerical problems in optics. It begins by defining light and common light phenomena like shadows and rainbows. It then discusses the branch of optics called geometric optics and focuses on key definitions for absorption, refraction, diffraction, and dispersion. The document provides examples and explanations of reflection, refraction, Snell's law, total internal reflection, and dispersion using a prism. It also discusses lenses, mirrors, and optical systems.
Making a rainbow
The document summarizes two experiments conducted to understand how rainbows are formed. In the first experiment, the students used a hose and spray bottle to create water droplets in the air when the sun was behind them, allowing them to see a rainbow. In the second experiment, they used a prism and flashlight to refract light into a rainbow. The document concludes that rainbows are caused by the refraction and dispersion of white light into colors by water droplets, as explained by Sir Isaac Newton. It also discusses the origin of the expression "a pot of gold at the end of the rainbow."
Yashvi s.pawar phy project (4).pptx
This document discusses the phenomenon of refraction of light and its applications. It begins by acknowledging those who helped with the project. Then it covers topics like how refraction occurs in nature through examples like vision and mirages. It explains the laws of refraction like Snell's law and total internal reflection. Applications of refraction discussed include lenses, fiber optics, and spectrometers.
Lights lesson plan
The document provides objectives and lesson plans for a lesson on light refraction, dispersion, and the relationship between color and energy. The key points are:
- Students will learn about refraction of light rays using a prism, how this causes dispersion and separates white light into the visible color spectrum.
- They will explain how the colors are arranged from red having the lowest energy and being least bent, to violet having the highest energy and being most bent.
- Activities include demonstrating refraction and dispersion using a prism, analyzing how colors appear after passing through, and relating wavelength and frequency to energy levels of different colors.

Describing and Interpreting an Immersive Learning Case with the Immersion Cub...
Current descriptions of immersive learning cases are often difficult or impossible to compare. This is due to a myriad of different options on what details to include, which aspects are relevant, and on the descriptive approaches employed. Also, these aspects often combine very specific details with more general guidelines or indicate intents and rationales without clarifying their implementation. In this paper we provide a method to describe immersive learning cases that is structured to enable comparisons, yet flexible enough to allow researchers and practitioners to decide which aspects to include. This method leverages a taxonomy that classifies educational aspects at three levels (uses, practices, and strategies) and then utilizes two frameworks, the Immersive Learning Brain and the Immersion Cube, to enable a structured description and interpretation of immersive learning cases. The method is then demonstrated on a published immersive learning case on training for wind turbine maintenance using virtual reality. Applying the method results in a structured artifact, the Immersive Learning Case Sheet, that tags the case with its proximal uses, practices, and strategies, and refines the free text case description to ensure that matching details are included. This contribution is thus a case description method in support of future comparative research of immersive learning cases. We then discuss how the resulting description and interpretation can be leveraged to change immersion learning cases, by enriching them (considering low-effort changes or additions) or innovating (exploring more challenging avenues of transformation). The method holds significant promise to support better-grounded research in immersive learning.
The binding of cosmological structures by massless topological defects
Assuming spherical symmetry and weak field, it is shown that if one solves the Poisson equation or the Einstein field
equations sourced by a topological defect, i.e. a singularity of a very specific form, the result is a localized gravitational
field capable of driving flat rotation (i.e. Keplerian circular orbits at a constant speed for all radii) of test masses on a thin
spherical shell without any underlying mass. Moreover, a large-scale structure which exploits this solution by assembling
concentrically a number of such topological defects can establish a flat stellar or galactic rotation curve, and can also deflect
light in the same manner as an equipotential (isothermal) sphere. Thus, the need for dark matter or modified gravity theory is
mitigated, at least in part.

The cost of acquiring information by natural selection
This is a short talk that I gave at the Banff International Research Station workshop on Modeling and Theory in Population Biology. The idea is to try to understand how the burden of natural selection relates to the amount of information that selection puts into the genome.
It's based on the first part of this research paper:

Applied Science: Thermodynamics, Laws & Methodology.pdf
When I was asked to give a companion lecture in support of ‘The Philosophy of Science’ (https://shorturl.at/4pUXz) I decided not to walk through the detail of the many methodologies in order of use. Instead, I chose to employ a long standing, and ongoing, scientific development as an exemplar. And so, I chose the ever evolving story of Thermodynamics as a scientific investigation at its best.
Conducted over a period of >200 years, Thermodynamics R&D, and application, benefitted from the highest levels of professionalism, collaboration, and technical thoroughness. New layers of application, methodology, and practice were made possible by the progressive advance of technology. In turn, this has seen measurement and modelling accuracy continually improved at a micro and macro level.
Perhaps most importantly, Thermodynamics rapidly became a primary tool in the advance of applied science/engineering/technology, spanning micro-tech, to aerospace and cosmology. I can think of no better a story to illustrate the breadth of scientific methodologies and applications at their best.
The debris of the ‘last major merger’ is dynamically young
The Milky Way’s (MW) inner stellar halo contains an [Fe/H]-rich component with highly eccentric orbits, often referred to as the
‘last major merger.’ Hypotheses for the origin of this component include Gaia-Sausage/Enceladus (GSE), where the progenitor
collided with the MW proto-disc 8–11 Gyr ago, and the Virgo Radial Merger (VRM), where the progenitor collided with the
MW disc within the last 3 Gyr. These two scenarios make different predictions about observable structure in local phase space,
because the morphology of debris depends on how long it has had to phase mix. The recently identified phase-space folds in Gaia
DR3 have positive caustic velocities, making them fundamentally different than the phase-mixed chevrons found in simulations
at late times. Roughly 20 per cent of the stars in the prograde local stellar halo are associated with the observed caustics. Based
on a simple phase-mixing model, the observed number of caustics are consistent with a merger that occurred 1–2 Gyr ago.
We also compare the observed phase-space distribution to FIRE-2 Latte simulations of GSE-like mergers, using a quantitative
measurement of phase mixing (2D causticality). The observed local phase-space distribution best matches the simulated data
1–2 Gyr after collision, and certainly not later than 3 Gyr. This is further evidence that the progenitor of the ‘last major merger’
did not collide with the MW proto-disc at early times, as is thought for the GSE, but instead collided with the MW disc within
the last few Gyr, consistent with the body of work surrounding the VRM.
