Two beam of red and violet colors are made to pass separately through a prism (angle of the prism is `60^(@)`). In the position of minimum deviation, the angle of refraction will be

A

`30^(@)` for both the colours

B

Greater for the violet colour

C

Greater for the red colour

D

Equal but not `30^(@)` for both the colours

Text Solution

Verified by Experts

The correct Answer is:
A
In case of minimum deviation
angle of refraction (r ) = `(A)/(2) = 30^(@)`.
