uses of refraction

Let us now see what happens when a ray of light is incident on the boundary separating the two media having different densities. A part of the light gets reflected and rest of the light changes its direction as it enters the second medium. The diagram shows how the light gets refracted..

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

It has higher density, transparency and refracting power than ordinary glass. Hence used for making optical instruments. It is also used for ornament purpose..

Optical Centre - It is the centre of a lens. It is denoted by the letter O. A ray of light passing through the optical centre of a lens does not suffer any deviation. It is also referred to as optic cent..

As the wave is refracted, it is bent down gradually rather than sharply. However, below the ionised layer, the incident and refracted rays follow paths that are exactly the same as they would have been if reflection had taken place from a surface located at a greater heigh..

According to Sir Issac Newton's Corpuscular Theory, a luminous body continuously emits tiny, light and elastic particles called corpuscles in all directions. When these particles fall on the retina of the eye, they produce the sensation of vision. This theory could explain a number of phenomena con..

Telescopes - Telescope is an optical instrument which is used for viewing heavenly bodies and distant objects. There are basically two types of telescopes: refracting telescope reflecting telescope Refraction Telescope Reflection Telescope Refracting telescop..

A glass plate ( m = 1.5) is used as a polarizer. Obtain the polarizing angle of incidence. What is the angle of refraction when the reflected light is plane polarize..

The previous chapter dealt with the refraction of light by lenses and also about the formation of various types of images by a lens for different positions of the object. In this chapter let us find out how lenses are used in optical instruments like microscopes and telesc..
