Question

7. The prism angle and refractive index for a prism are 60" and root 2
respectively. The angle of minimum deviation will be
(A) 15
(B) 30
(C) 45°
(D) 60"

​

Answer 1

Explanation:

(uo-1)A=d

where,uo= refractive index

A =angle if prisom

d=angle of deviation

root 2 value =1.414

A=60°

(1.414-1)60=d

0.414×60=d

d=24.84
