Question

The angle of a prism is 60° and its refractive index is 5. The angle of
minimum deviation suffered by a ray of light in passing through it is​

Answer 1

Answer:

2sin⁻¹(5/2)-60

Explanation:

Let the minimum deviation be x

The relation between μand minimum deviation is⇒

μ = sin[(A+x)/2]/sin(A/2)

5=sin[(60+x)/2]/sin(60/2)

On solving ⇒ x=2sin⁻¹(5/2)-60
