Question

Angle of deviation decreases first and then increase with

increase in ________. ( )

a) Angle of minimum deviation

b) Angle of emergence

c) Angle of prism

d) Angle of Incidence​

Answer 1

Explanation:

For a prism and a perticular angle of incidence the first angle of deviation is independent of angle of prsim but second of angle of deviation increases as the angle of prism increases because angle of incidence of the refracted ray in the prism at the second surface increases.
