Question

Refracting angle o f a prism `A=60^@` and its refractive index is `n=3//2`. What is angle of incidence i to get minimum deviation. Also, find the minimum deviation. Assume the surrounding medium to be air `(n=1)`.

Answer 1

Correct Answer - `sin^(-1) ((3)/(4)), 2 sin^(-1) ((3)/(4)) -(pi)/(3)`
