Question

A ray is incident at angle of incidence i on
one surface of a small angle prime (with
angle of prism A) and emerges normally
from the opposite surface. If the refractive
index of the material of the prism is u, ther
the angle of incidence is nearly equal to​

Answer 1

Answer:

Now as we know in a prism, a small angle of prism plus angle of deviation in a prism is equal to the sum of angle of incidence and angle of emergence. So this is the required angle of incidence such that the prism has small angle A and emerges normally from the opposite surface. So this is the required answer.
