Prove that it is impossible to see through adjacent sides of a square block of glass with index of refraction 1.5.

A ray incident on the face of a prism is refracted and escape through an adjacent face. What is the maximum permissible angle of the prism, if it is made of glass with a refractive index of mu=1.5 ?

The optical path of a monochromatic light is same if it goes through 4.0 cm of glass or 4.5 cm of water. If the refractive index of glass is 1.53, the refractive index of the water is

Light reflected from the surface of glass plate of refractive index 1.57 is linearly polarised. Calculate the angle of refraction in glass.

The refractive index of glass is 1.9 . If light travels through a glass slab of thickness d in time t and takes the same time to travel through a transparent beaker filled with water upto a level of 1.5 d, then the refractive index of water is
