Question

2 points
10.A ray of light incident at an
angle of incidence 40°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, min=?

as min=2i-A

min=2(48)-60

min=36°
