Question

The angle of incidence of light ray in an equilateral prism is 45 degrees; What is the angle of deviation of light if the light ray in the prism is parallel to the ground?
PLEASE HELP URGENT !!!!!!!!!!!!!!!!

Answer 1

Answer:

So, the angle of deviation is 30 degrees. Hence, this is the required solution

Explanation:

Hope it Will help you

Answer 2

Answer:

The answer is 30 degrees.

Explanation:

Given that,

Angle of incidence, i = 45°

The refracting angle of the prism, r = 60°

We need to find the angle of deviation of the prism. We know that the relation between the angle of incidence, angle of deviation and the angle of prism. It is given by :

delta=2i-r

=2(45)- 60

=30 degree
