What is the angle of incidence for an equilateral prism of refractive index `sqrt(3)` so that the ray si parallel to the base inside the prism?

A

`30^(@)`

B

`45^(@)`

C

`60^(@)`

D

`75^(@)`

Text Solution

Verified by Experts

The ray retraces its path after reflection from the silvered face AC. Therefore, `angleARQ=90^(@)`. As is clear from the figure, the angle of reflection RQN at face AB is `30^(@)`.
