Application +4 | -1

Under minimum deviation condition in a prism, if a ray is incident at an angle

{30^ \circ }

, the angle between the emergent ray and the second refracting surface of the prism is

View answer and explanation

Correct option: D

{60^ \circ }

Option D (

{60^ \circ }

) is correct because under minimum deviation, the angle of incidence equals the angle of emergence, and the angle between the emergent ray and the second refracting surface is 90 degrees minus the angle of emergence.
