Question

A ray of light incident at an angle of incidence 48degree on a
prism of refracting angle 60° suffers minimum
deviation. Calculate the angle of minimum deviation.​

Answer 1

Answer:

Given,

Angle of incidence, i = 48°

Refracting angle, A = 60°

Angle of minimum deviation, δmin =?

As δmin = 2i – A

δmin = 2(48) – 60

δmin = 36°
