The two perpendicular faces of a right angled isosceles prism are silvered. Prove that a light ray incident on the third face (hypotenuse face) will emerge from the prism parallel to the initial direction.

A ray of light is normally incident on one face of an equilateral glass prism. Answer the following : (a) What is the angle of incidence on the first face of the prism? (b) What is the angle of refraction from the first face of the prism ? (c) What will be the angle of incidence at the second face of the prism ? (d) Will the light ray suffer minimum deviation by the prism ?

If a light ray incidents normally on one of the faces of the prism of refractive index 2 and the emergent ray just grazes the second face of the prism, then the angle of deviation is
