Question

The refractive index of prism is √2 and its refrcting angle is 60° for minimum deviation the angle of incidence will​

Answer 1

Answer:

30°

Step-by-step explanation:

u = [sin(a+d)/2]/sin(a/2)

= [sin(60+d)/2]/sin30

(√2)× 0.5 = sin(60+d)/2

sin(60+d)/2 = 1/√2

(60 +d)/2 = 45

d = (45-30)×2 = 30°
