A ray of light incident at an angle of incidence `i_(1)` passes through an equilateral glass prism such that the refracted ray inside the prism is parallel to its base and emerges at an angle of emergence `i_(2)`.
(i) How is the angle of emergence `'i_(1)'` related to the angle of incidence `'i_(1)'` ?
(Ii) What can you say about the angle of deviation in such a situation ?

Text Solution

Verified by Experts

The correct Answer is:
(i) `i_(2)=i_(1)`
(ii) angle of deviation is minimum.
