A prism can have a maximum refracting angle of (C = critical angle for the material of the prism)

A ray of light is incident on a prism of refracting angle A. if theta_(C) is the critical angle for the material of the prism with respect to the surrounding air, then:

(a) Draw a ray diagram showing the passage of light through a glass prism. Hence obtain a relation between the angles of deviation, incidence and emergence and angle of prism. (b) Show that no ray can pass through a prism whose refracting angle A is greater than twice the critical angle for the material of the prism.

As shown in Fig. PQ is a ray incident on prism ABC . Show the corresponding refracted and emergent rays. The critical angle for the material of the prism is 45^@ . What is refractive index of the material of prism ? .

The angle of incidence for a ray of light at a refracting surface of a prism is 45^(@) . The angle of prism is 60^(@) . If the ray suffers minimum deviation through the prism, the angle of minimum deviation and refractive index of the material of the prism respectively, are :
