Question 390: Ray Optics

Question

A rays of light is incident on a 60o prism at the minimum deviation position. The angle of refraction at the first face (i.e., incident face) of the prism is

Accepted Answer

Angle of prism, A = r
1
+ r
2
For minimum deviation r
1
= r
2
= r
$$ 	herefore $$  A = 2r
Given, A = 60ÃÂ°
Hence, r = $${A \over 2}$$ = $${{60^\circ } \over 2}$$ = 30
