The angle of deviation produced in the direction of light when it is refracted from the refracting surface is

What is the angle of deviation due to refraction of a ray of light incident perpendicularly on a refraction surface?

An equilateral glass prism of refractive index 1.5 is immersed in water. Find the angle of deviation produced when a ray of light is incident at 42^(@) on one face of the prism. (Refractive index of water = 1.33)

A ray of light passes from air into a liquid. The glancing angle is 30^(@) . The deviation produced in the ray of light is 15^(@) . The refractive index of liquid is :

The angle of minimum deviation for an incident light ray on an equilateral prism is equal to its refracting angle. The refractive index of its material is

The angle of minimum deviation for an incident light ray on an equilateral prism is equal to its refracting angle. The refractive index of its material is

The angle of deviation of a ray of light refracted through a parallel glass slab is
