Question

Draw a graph showing variation of angle of deviation (D) with angle of incidence(i) of rays passing through a prism. Name the two factors on which angle ofminimum deviation (sigma) depends​

Answer 1

Answer:

The above diagram shows the path of light traced when it passes through a prism such that the angle of deviation of light is minimum.

When a light deviates with a minimum amount, angle of incidence i and the angle of emergence e are equal.

Also, the light inside the prism passes parallel to the base of prism BC.
