Question

How the angle of deviation varies with angle of incidence of prism​

Answer 1

Answer:

ray of light suffers two refractions on passing through a prism. ... The angle through which the emergent ray deviates from the direction of incident ray is called angle of deviation 'd'. As the angle of incidence is increased, angle of deviation 'd' decreases and reaches minimum value.
