Question

a ray of light incident at an angle of 45° on a equilateral prism is deviated through an angle of 40°.Calculate the angle of emergence of the ray

Answer 1

Answer:

Angle of emergence of light through the prism is 55 degree

Explanation:

As we know that angle of deviation through the prism is given by the formula

$\delta = i + e - A$

here we know that angle of deviation of light is given as

$\delta = 40^o$

since prism is equilateral prism so we have

A = 60

also angle of incidence is given to us

$i = 45^o$

so we have

$40^o = 45 + e - 60^o$

$e = 55^o$
