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 =30∘+30∘−60∘=0∘ ∴ 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!
