Under minimum deviation condition in a prism, if a ray is incident at an angle `30^(@)`, the angle between the emergent ray and the second refracting surface of the prism is

A

`0^(@)`

B

`30^(@)`

C

`45^(@)`

D

`60^(@)`

Text Solution

Verified by Experts

The correct Answer is:
D
In minimum deviation `i=e=30^(@)`, so angle between emergent ray and second refracting surface is `90^(@)-30^(@)=60^(@)`
