Application +4 | -1

A ray of light is incident at an angle of

60^\circ

on one face of a prism of angle

30^\circ .

The emergent ray of light makes an angle of

30^\circ

with incident ray. The angle made by the emergent ray with second face of prism will be

View answer and explanation

Correct option: B

90^\circ

Option B (

90^\circ

) is correct because the emergent ray grazes the second face of the prism, meaning the angle of emergence is 0 degrees.
