Questions
A ray of light is incident at an angle of 60° on one face of a prism of angle 30°. The ray emerging out of the prism makes an angle of 30° with the incident ray. The emergent ray is
detailed solution
Correct option is A
We know that δ=i+e−A⇒e=δ+A−i=30o+30o−60o=0o∴Emergent ray will be perpendicular to the face. Therefore it will make an angle of 90' with the face through which it emerges.Talk to our academic expert!
