A ray of light incident on one of the face of a prism as shown. After refraction through this surface ray is incident on base of the prism. The refractive index of the prism is `sqrt(3)`. The net deviation of the ray due to prism is

A

`60^(@)` clockwise

B

`104^(@)` clockwise

C

`104^(@)` anticlockwise

D

`166^(@)` clockwise

Text Solution

Verified by Experts

The correct Answer is:
D

`1.sin60^(@)=sqrt(3)sinthetaimpliesr=30^(@)`
Total deviation `=(60-30^(@))+(180-2xx37^(@))+(60^(@)-30^(@))`
`=166^(@)` clockwise
