Refraction

Refracting Telescope

A light is incident on a refractive medium. The light is partially reflected and partially refracted. If both the reflected and refracted rays are mutually perpendicular, then determine the angle of refraction. Refractive index of medium is 1.47.

The angle of minimum deviation of a prism of refractive index sqrt(3) is equal to its refracting angle. Then the refracting angle of that prism is

The angle of minimum deviation of a prism of refractive index sqrt(3) is equal to its refracting angle. Then the refracting angle of the prism is

Refractive Index

A ray of light is incident normally on one of the refracting surfaces of prism of refracting angle 60^@ . The emergent ray grazes the other refracting surface. The refractive index of the material of the prism is

Find the refractive index of water with respect to glass if the refractive index of water is 4/3 and the refractive index of glass is 3/2.
