Question

what is an angle of deviation when the angle of incidence is 30 degree angle of emergence is also 30 degree and Angle of prism is 60 degree

Answer 1

The angle of deviation is zero, as there is no deviation occurs.

Explanation:

In the above given case the angle of incidence and angle of emergence are equal while the angle of the slab for the prism that is being used is 60.

Now we know that the sum of the angles at which the ray is incident or emerging is equal to Sum of two angles of deviation in prism then putting this in the form of formula we get:-

A+D = I+E

Here I is equal to E and the value of it is 30.

A + D = 30 + 30

⇒ 60 + D =60 ⇒ D= 0

This shows that deviation of the angle from incidence is zero.
