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
Text Solution
Verified by ExpertsThe correct answer is:
A
We know that 
= 
Emergent ray will be perpendicular to the face.
Therefore it will make an angle of 90° with the face through which it emerges.
