Answer:

Minimum Angle of Deviation for a Prism

At the minimum deviation, Dm therefracted ray inside the prismbecomes parallel to its base, i.e. i = e ⇒ r1 = r2 = r, then r = A/2 and Dm = 2i – A, where i is the angle of emergence, r1 and r2 are the angles of refractionand A is the angle of the prism.
