Question

define angle of minimum deviation in which page the answer is​

Answer 1

Answer:

In a prism, the angle of deviation decreases with increase in the angle of incidence up to a particular angle. This angle of incidence where the angle of deviation in a prism is minimum is called the minimum deviation position of the prism and that very deviation angle is known as the minimum angle of deviation.

Explanation:

Angle of minimum deviation is the minimum angle at which the angle of incidence will be equal to the angle of emergence and the refracted ray will be parallel to the base of the prism.
