Answer
The angle of deviation (δ) produced by a prism first decreases with the increase in angle of incidence (i) and reaches to a minimum value at a certain angle of incidence. With further increase in angle of incidence, angle of deviation also increases.
The graph below shows the variation of angle of deviation with the angle of incidence:
