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 a prism of refracting angle A,. The emergent ray grazes the other refracting surface. Find the refractive index of the material ofprism.

A glass prism has refractive index sqrt(2) and refracting angle 30^(@) . One of the refracting surface of the prism is silvered. A beam of monchromatic light will retrace it path it its angle of incidence on the unsilvered refracting surface of the prism is
