Spherical mirrors can be either concave or convex depending on whether the surface is bent inwards or bulges outwards. They are constructed from glass with one surface carved into a spherical shape for reflection. Spherical mirrors are used in various applications such as shaving, dentistry, vehicle headlights, solar energy collection, and reflecting telescopes. Concave mirrors reflect and focus light rays at a focal point, forming different image types depending on the object distance. Convex mirrors diverge light rays and always produce a virtual, upright, and diminished image regardless of object distance. They are commonly used as vehicle side mirrors and on road curves to increase visibility.

- Reflection of light occurs when light bounces off a surface. The angle of incidence is equal to the angle of reflection.
- Refraction occurs when light changes speed and direction as it passes from one medium to another. The ratio of the sines of the angles of incidence and refraction is a constant value called the refractive index.
- Experiments can show that light reflects according to the law of reflection and refracts at different angles depending on the medium, such as when passing through glass blocks. Measurements are used to determine refractive indices.

Reflection of light
The document discusses key concepts related to reflection of light, including:
1) Luminous objects generate their own light, while illuminated objects reflect light. Reflection occurs when light bounces off a smooth, shiny surface at the same angle as it hits the surface.
2) The incident ray strikes the mirror, and the reflected ray leaves the mirror and strikes the eye, forming the line of sight from the image to the eye.
3) The angle of incidence equals the angle of reflection.

Light ppt
Light is part of the electromagnetic spectrum that is visible to the human eye. It travels in straight lines called rays. Luminous objects like light bulbs and the sun emit their own light, while non-luminous objects like tables reflect light. Reflection is when light rays bounce off a surface, following the laws that the angle of incidence equals the angle of reflection and the reflected ray, incident ray, and normal all lie in the same plane. Refraction is when light changes speed and direction when passing from one medium to another due to differences in optical density, following Snell's law relating the sines of the angles of incidence and refraction. This causes phenomena like objects in water appearing bent and pools seeming shal
Forces and motion
Forces can make objects move, stop, or change shape. There are different types of forces including gravity, electric force, magnetic force, and friction. Forces can also distort objects temporarily or permanently. Forces affect motion by making things move, stopping moving objects, and changing the direction of moving objects. Machines are devices that use or convert energy. They can be powered by human energy, natural energy sources like water or wind, or electricity. Machines produce various types of movement or thermal effects and can process information.
Refraction
When light travelling in one medium falls on the surface of second medium the following three effect may occur.
1:- A part of incident light is reflected back into the same medium. This is called Reflection of light.
2:- A part of light is passes through the medium.This Is known as Refraction of light.
3:- And remaining part of the light is absorbed by the surface on which the light fall. This is known as Absorption of light.

Light - Physics
Light is electromagnetic radiation that allows us to see. It can travel without a medium and includes visible light. The sun, flames, and light bulbs are luminous as they produce their own light, while objects like the moon reflect light and are non-luminous. Materials can be opaque and block light, transparent and let light pass through clearly, or translucent and let some light pass through blurring images. Shadows are formed when an opaque object blocks light, which travels in straight lines. Solar and lunar eclipses occur due to the alignment of the sun, earth, and moon. A pinhole camera uses a small opening to project an image using the principle that light travels in straight lines.
Reflection of light (Physics)
Light propagates in straight lines and can be reflected, refracted, and diffracted when interacting with matter. Reflection occurs when light hits a smooth surface and bounces back into the same medium at the same angle. Regular reflection occurs from plane mirrors where the angle of incidence equals the angle of reflection. Spherical mirrors can be concave or convex. Concave mirrors form real, inverted images, while convex mirrors form virtual, upright images. The mirror equation relates the focal length and distances of the object and image.
Plane mirrors
1. The document discusses the properties and behavior of light when reflected off plane mirrors. It states that light reflects off mirrors at an equal angle to the normal as the incident light.
2. The virtual image formed by a plane mirror appears to be located behind the mirror and is the same distance from the mirror as the real object is in front of it.
3. When two mirrors are placed at an angle to each other, the number of images seen is equal to 360 degrees divided by the angle between the mirrors. Multiple reflections within the mirror system can produce multiple virtual images.
Reflection and refraction
1) Light behaves both as a wave and particle. It undergoes various phenomena like reflection, refraction, diffraction etc. which were explained by wave theory.
2) Reflection of light follows the laws - the angle of incidence equals the angle of reflection, and the incident ray, normal and reflected ray lie in the same plane. Reflection can be regular from smooth surfaces or diffuse from rough surfaces.
3) Spherical mirrors are either concave or convex. Concave mirrors converge parallel rays to a focal point, while convex mirrors diverge them from a focal point behind the mirror. Images formed depend on the position of the object.
3. 15. light
1) Light travels in a straight line. An experiment using a pipe or tube shows that light from a candle cannot be seen if the pipe is bent, demonstrating that light travels in a straight path.
2) When light hits a mirror, it changes direction, which is called reflection. An experiment using a mirror and torch shows that moving the torch or mirror changes the direction of the reflected light.
3) A plane mirror forms an image that is erect, the same size as the object, and the same distance from the mirror as the object. The image is also virtual and left and right are reversed in the image.

Basic optics
Optics is the study of light, including its interactions with matter. There are three main subfields: geometrical optics studies light as rays, physical optics studies light as waves, and quantum optics studies light as particles. Mirrors form images through the reflection of light rays according to specific rules. Plane mirrors form virtual upright images that are laterally inverted. Spherical mirrors can be concave or convex and form images using rules for tracing the path of light rays. Constructing ray diagrams involves using rays that pass through the center of curvature, focal point, or pole to locate the image point.
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.

The centroid has several important properties: it is the center of the object, the center of gravity, and always lies inside the object. It represents the balance point of the object. The centroid, center of mass, and center of gravity are often used interchangeably for simple rigid objects with uniform density since they refer to the same point. Knowing the centroid has applications in keeping structures balanced and in calculating stresses and deflections.

formation_of_pn_juction.pptx
When a p-type semiconductor is joined with an n-type semiconductor, a p-n junction is formed. Electrons from the n-type region diffuse across the junction and combine with holes from the p-type region, forming a depletion layer devoid of charge carriers. The diffusion of charge carriers continues until an electric field is produced that prevents further diffusion. When a voltage is applied across the junction, current can flow as the majority charge carriers are encouraged to diffuse in one direction.
Brewster’s_Law
Brewster's law states that when light passes from one transparent medium into another at a particular angle known as Brewster's angle, the reflected light will be completely polarized. The document defines Brewster's angle using the refractive indices of the two media and shows the relationship between Brewster's angle and the critical angle. It provides examples of how Brewster's law is applied in polarized sunglasses and photography filters to reduce glare from reflections at surfaces.
Presentation1.pptx
Light entering a prism is dispersed due to differences in how much each wavelength of light is refracted. The red color of light has the longest wavelength and is refracted the least, so it deviates the minimum amount when passing through a prism. The different colors of light spread out as they exit the prism due to their varying degrees of refraction.
Diffraction and polarization
This document discusses diffraction, polarization, and Brewster's law. It defines diffraction as the bending of light around corners such that it spreads out. It describes two types of diffraction: Fresnel and Fraunhofer. Polarization is caused by the wave nature of electromagnetic radiation and results in three types: linear, circular, and elliptical polarization. Brewster's law states that unpolarized light experiences maximum polarization at the angle whose tangent is the refractive index, known as Brewster's angle.

SPHERICAL MIRROR.pptx
- 2. SPHERICAL MIRROR • A spherical mirror can be a concave or a convex mirror depending upon the surface of the reflection. If it is bulged out then it is a convex spherical mirror whereas if it is bent inwards it is termed as a concave spherical mirror. • A typical spherical mirror is a part of a big sphere of which the cut-out has been taken. • A spherical mirror is a mirror that has the shape of a piece carved out of a sphere. • A spherical mirror is categorised into two forms, concave and convex. • Spherical mirrors are the mirrors that are curved in shape and are the part of an sphere. • Spherical mirrors are constructed from the glass. One surface of the spherical part is other part is used for reflection.
- 3. USE OF SPHERICAL MIRROR • Spherical mirrors are used by all in day-to-day life. • It is important that students have a better understanding of the application of spherical mirrors so that they grasp the concept properly. • Students often find problems when dealing with the concept because it can prove to be complicated. • However, this concept is important because questions from this concept do come in exams. • This article has a detailed explanation of the application of spherical mirrors. • Students can find spherical mirror examples which will help them understand the concept. • The article has explained in detail the examples of concave and convex mirrors and their definitions, which are important for students to understand. After reading this article students will be able to write the uses of spherical mirrors and ace their exams.
- 4. SHPERICAL TYPE 1. Concave mirror:- The definition of a concave mirror says that when a spherical mirror surface is painted out wards and its inner surface is reflecting, it is called a Concave A concave mirror is a spherical mirror, which has a reflecting surface, dented inwards. Concave mirrors reflect and focus incoming light rays (parallel) at a point, called the focus point. Depending on the distance of an object from the reflecting surface, different types of images are formed. Concave mirrors are also called converging mirrors since light rays converge after reflection at concave mirrors.
- 5. USE OF CONCAVE MIRROR • Men use them while shaving. • Dentists use them to see the back of teeth. • They are used to produce parallel beams of light in torches, vehicle headlights and searchlights. • They are used as concentrators in solar cookers and furnaces. • They are used in reflecting telescopes
- 6. SHPERICAL TYPE 2. Convex Mirror:- The part of the hollow sphere which is silver painted from the inside and the outer surface is used for the reflection purpose and is known as a convex mirror. The figure shows a convex mirror. • A convex mirror is also referred to as a diverging mirror because, when light rays hit its reflecting surface, they diverge. • Whatever the object's distance from the convex mirror, it always produces a virtual, erect and diminished image. • Convex mirrors do not focus the light ray toward a point as the rays after hitting always diverge.
- 7. USES OF CONVEX MIRRORS • We have seen these mirrors on the sides of vehicles. Convex side view mirrors show a larger area in a small space. • They are placed at curves of roads to give a view of the bend of the road. • Convex mirrors are also used in reflecting telescopes.
