Find out the angle of deviation

(a) How does the angle of deviation produced by a prism change with increase in the angle of incidence. Draw a curve showing the variation in the angle of deviation with the angle of incidence at a prism surface. (b) Using the curve in part (a) above, how do you infer that for a given prism, the angle of minimum deviation delta_("min") is unique for a given light.

How does the angle of deviation vary with the angle of incidence in case of a prism ?What is the angle fo minimum deviation?

How does the angle of deviation formed by a prism change with the increase in the angle of incidence ? Draw a graph showing the variation in the angle of deviation with the angle of incidence at a prism surface.

How does the angle of deviation depend on the refracting angle of the prism?
