Microscope parts
The document describes the main parts of a light microscope and their functions. It includes labels and descriptions for each part: the eyepiece contains the ocular lens, the coarse adjustment knob moves the stage up and down for focusing, and the fine adjustment knob moves the stage slightly to sharpen the image. As the power of magnification increases, the level of magnification and detail visible also increases.
Microscopy
A microscope is a tool that magnifies tiny objects and living organisms so they can be seen more clearly. It has magnifying power that makes things look bigger and resolving power that allows it to distinguish small gaps. A light microscope uses light to illuminate the object being observed. The main parts of a microscope include the arm, base, eyepiece, body tube, coarse and fine adjustment knobs, light source, diaphragm, stage and clips, objective lenses, revolving nosepiece, and inclination joint. When using a microscope, one should always start with the low power objective, use the coarse focus carefully, and never use it at higher magnifications.

Microscope
The document describes the main components of a light microscope and their functions. It includes:
1) The eye piece or ocular, which is the lens used to view the specimen.
2) The body tube, which supports the eyepiece.
3) The revolving nosepiece, which holds the objective lenses and allows them to be changed.
4) The stage, which holds the specimen in place under the objectives.
Types of Microscope
Microscopes are instruments designed to produce magnified images of small objects. They must accomplish three tasks: produce a magnified image, separate details in the image, and render details visible. There are different types of microscopes including simple, compound, stereoscopic, electron, scanning electron, and transmission electron microscopes. Electron microscopes use a beam of electrons instead of light to magnify images and can achieve higher magnifications than light microscopes. Confocal laser scanning microscopes use a laser beam to generate 3D images of thick specimens.
Transport mechanism
The cell membrane is selectively permeable, allowing only a limited number of materials to diffuse through its lipid bilayer. During passive transport, materials move by simple diffusion or by facilitated diffusion through the membrane, down their concentration gradient.
The microscope grade 7
The document summarizes the history and components of microscopes.

Levels of biological organization
Levels of biological organization range from the smallest units such as atoms and molecules, to cells, tissues, organs, organ systems, whole organisms, populations of the same species, communities of multiple interacting species, ecosystems, and ultimately the biosphere of all life on Earth. Cells are the smallest living units capable of basic functions like metabolism and reproduction. Tissues are groups of similar cell types that work together, while organs consist of multiple tissue types organized to perform specific functions. Organ systems group related organs to carry out broader functions.
The microscope
The document discusses the history of the microscope and identifies the key parts and their functions, including the eyepiece, objective lenses, stage, light source, and how they work together to produce a virtual magnified image, with light from the condenser focusing on the specimen through the objectives and eyepiece. Images are formed when light from the object passes through the objective lens to form a real inverted intermediate image that the eyepiece further magnifies into a final virtual upright image for viewing.

It details the various parts of a compound microscope, including the stage, objective lenses, eyepiece, condenser, and diaphragm. It explains that changing the objective lens allows higher magnification and that oil immersion objectives provide the highest magnification of 100x.
Electrical Energy
The document discusses key concepts about electrical energy including:
- Atoms are made up of a nucleus surrounded by electrons that carry a negative charge. Protons in the nucleus carry a positive charge while neutrons carry no charge.
- Static electricity occurs when surfaces rub against each other, transferring electrons between them and building up positive or negative charges.
- Electric current involves the flow of electrons along a wire or conductor, which can be measured in amps. Voltage measures the energy supplied by these charges and is measured in volts.
Simple & compound microscope PPT
1. A compound microscope uses two lenses, an objective lens with a short focal length that magnifies the object, and an eyepiece lens that further magnifies the image from the objective lens and brings it into the visible range.
2. The objective lens produces a real, inverted intermediate image of the specimen that is enlarged, and the eyepiece lens magnifies this intermediate image and produces a final virtual image that is both enlarged and upright.
3. The magnifying power of a compound microscope is calculated as the ratio of the angle subtended by the final magnified image to the angle subtended by the actual specimen.

A sphygmomanometer, also known as a blood pressure meter, measures blood pressure using an inflatable cuff and measuring unit. It detects the systolic and diastolic pressures as the cuff pressure is released and blood flow is heard through a stethoscope. Sphygmomanometers vary in price from 600 to 6000 rupees.
Light microscopy
this presentation deals with the introduction of some of the commonly used optical microscopes in forensic labs; compound microscope, stereoscopic microscope, comparison microscope, fluorescence microscope and polarized microscope.
Flame photometry
Flame photometry is a technique that uses the characteristic wavelengths of light emitted from atoms excited in a flame to determine the concentration of certain metal ions in solutions. When a sample containing metal ions is introduced into a flame, the ions are atomized and excited to emit light of distinct wavelengths. The intensity of light emitted is directly proportional to the concentration of the metal ion in the sample. Common metal ions that can be analyzed using this technique include sodium, potassium, lithium, and calcium. Interferences from other ions may affect the results. Modern flame photometers use nebulizers to atomize samples, monochromators to select wavelengths, and detectors to measure light intensities.

Cell theory
Cells were first discovered in 1665 by Robert Hooke, who observed structures in cork under a microscope that resembled rooms of monks, which he called cells. The cell theory states that all living things are made of one or more cells, cells are the basic units of structure and function in organisms, and cells only come from preexisting cells. There are two main types of cells - prokaryotic cells which lack nuclei and have DNA throughout, and eukaryotic cells which have nuclei and membrane-bound organelles. Eukaryotic cells contain organelles that perform specific functions, and plant and animal cells contain both similar and different organelles such as chloroplasts in plant cells and lysosomes in animal cells.

Microscope notes
The microscope was developed in the 1600s by several people including Zacharias Janssen, who created the first microscope by combining two magnifying glasses, and Anton Von Leeuwenhoek, who created early modern microscopes. Robert Hooke used microscopes to discover and name cells. There are several types of microscopes including simple microscopes with two lenses, compound microscopes with multiple lenses allowing different magnifications, and stereomicroscopes with two eyepieces allowing 3D viewing of thick objects. The most powerful are electron microscopes, which can magnify over a million times using electron beams. Compound, simple, and stereomicroscopes use convex lenses to magnify objects.
Energy
Energy is the ability to do work or cause change and comes in various forms including mechanical, heat, chemical, electromagnetic, and nuclear energy. Mechanical energy is associated with motion and can be kinetic, from an object's movement, or potential, from its position. Energy can be transferred from one form to another through conversions without being created or destroyed according to the law of conservation of energy.
Work and power
Work is done when a force causes an object to move in the direction of the force. Work can be calculated using the formula Work = Force x Distance. Work is measured in joules, named after scientist James Joule. Power is a measure of how quickly work is done and is calculated by dividing work by time. Power is measured in watts, named after James Watt who helped advance steam engines.
Simple machinesnotes
The document discusses machines and simple machines. It explains that machines make work easier by increasing output force or distance through mechanical advantage. There are 6 simple machines: inclined plane, wedge, lever, screw, wheel and axle, and pulley. Simple machines are devices that do work with only one or two moving parts. Machines change the way work is done by exerting input force over a distance to produce output force. The output work of a machine can never exceed the input work due to friction.
Newton2ndnotes
Newton's 2nd law of motion states that an object will accelerate in the direction of an applied force. Gravity is a force that causes objects to accelerate towards Earth at 9.8 m/s^2. Newton's 3rd law states that for every action force, there is an equal and opposite reaction force - when one object exerts a force on a second object, the second object exerts an equal force back on the first. Centripetal force and the horizontal motion of satellites allows them to orbit planets in curved paths, while air resistance opposes the downward force of gravity on falling objects.
Newton1stnotes
Sir Isaac Newton discovered three laws of motion that describe how objects interact in the physical world. Newton's first law states that objects at rest will stay at rest and objects in motion will stay in motion unless acted on by an outside force. The document goes on to define key concepts related to Newton's laws such as inertia, balanced and unbalanced forces, different types of friction, and how friction can be overcome.
Motionnotes
This document defines and explains key concepts related to motion, including:
1) Motion involves the movement of an object from one point to another, which can be measured by distance and displacement. Distance is the length between two points, while displacement also considers direction of travel.
2) Speed, velocity, and acceleration are defined. Speed is the distance traveled over time. Velocity includes both speed and direction. Acceleration is the rate of change of velocity over time.
3) Momentum is the measure of how difficult it is to stop an object moving, calculated as the object's mass multiplied by its velocity. Mass is the amount of matter in an object, while weight depends on gravity.

- 1. The Microscope Image courtesy of: Microscopehelp.com Basic rules to using the microscope 1. You should always carry a microscope with two hands, one on the arm and the other under the base. 2. You should always start on the lowest power objective lens and should always leave the microscope on the low power lens when you finish using it. 3. You should use the Course adjustment only to focus the microscope at first, and then use the fine to get the image in perfect focus. Always use only the fine adjustment when using the high powered lens. 4. Always put the dust cover back on the microscope when you are not using it.
