Question

in minimum deviation position of prism,the angle of refraction is equal to ...
A)A
B)A/2
C)2A
D)A/3
pls give your answer with explanation​

Answer 1

In minimum deviation position, the refracted ray inside the prism is ....................... to the base.

ANSWER

When the deviation is minimum, then the incidence angle and emergence angle are equal and this is possible only when the refracted ray inside the prism is parallel to the base of prism.

Minimum deviation is given by δ=2i−A, where A is prism angle.
