Question

Under minimum deviation condition in a prism, if a ray is incident at an angle of 30, the angle between the emergent ray and the refracting surface of the prism is

Answer 1

In the case of minimum deviation 2i=A+δ.
And in the minimum deviation in a regular prism (angle of prism is 60 Degree) the angle of emergence is 30 degrees  and the angle between the refracting surface  and the emergent ray will be 150 degrees
