A ray of light is incident on the surface of a glass plate of refractive index 1.536 at the polarising angle.Calculate the angle of refraction.

If a ray of light travelling in glass enters into water will it bend towards or away from the normal?

A ray of light passes from air to glass (mu = 1.5) at an angle of 30^@ .Calculate angle of refraction.

Refractive indices of kerosene,turpentine and water are 1.44, 1,47 and 1.33 respectively, in which material does the light travel fastest and why?

A ray of light is incident on the glass prism at an angle of 40^@ .Find the angle of emergence,if the angle of prism is 60^@ and refractive index.

A ray of light is incident on a medium at polarising angle .What is the angle betweeen the relfected and refracted rays?

Refractive index of water w.r.t. air is 4/3 and that of glass w.r.t air is 2/3 what will be the refractive index of glass w.r.t water ?

The refractive index of water is 4//3 .How much time will light take to travel through a water column of length 500 m?

Glass of refractive index 1.5 is coated with a thin layer of thickness t and refractive index 1.8 . Light of wavelength lambda travelling in air is incident normally on the layer. It is partly reflected at the upper and the lower surfaces of the layer and the two reflected rays interface . If lambda = 648 nm , obtain the least value of t ("in" 10^(-8)m ) which the rays interface constructively.
