reflection and refraction mirror

IO incident ray OR l reflected ray OR refracted ray The diagram shows how the light gets refracted when it is traveling from one optical medium to another. Like reflection, refraction of light takes place according to certain laws. Before we state t..

Reflecting Telescope - Refraction Telescope The objective lens is replaced by a concave parabolic mirror of large aperture. The images in such telescopes are brighter and have a high resolving power compared to astronomical telescop..

Refraction of Light - Let us now see what happens when a ray of light is incident on the boundary separating the two mediums having different densities. A part of the light gets reflected and rest of the light changes its direction as it enters the second mediu..

Mirror formula is the relationship between object distance (u), image distance (v) and focal lengt..

Let AB be an object placed on the principal axis of a convex mirror of focal length f. u is the distance between the object and the mirror and v is the distance between the image and the mirror. But DE = AB and when the aperture is very small EF = PF. Equation (2) beco..

In the previous chapter we have seen how light gets reflected when it is incident on a surface. Now let us see what happens when a ray of light traveling from one medium to another medium of different densit..

Introduction - In the previous chapter we have seen how light gets reflected when it is incident on a surface. Now let us see what happens when a ray of light travelling in one medium enters another medium of different optical density. It is a matter of common experience that a spoon plac..

Mirage is an optical illusion, which occurs usually in deserts on hot summer days. On such a day, temperature of air near the earth is maximum and hence is rarer or lighter. The upper layers of air, which are relatively cool, are denser. A ray of light from the top of a tree travels from denser t..

Convex mirror is a spherical mirror whose reflecting surface is away from the center of the sphere of which the mirror is a par..
