. (a) How does the angle of deviation produced by a prism change with increase in the angle of incidence


(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 given prism, the angle of minimum deviation δmin is unique for the given light.

 

Best Answer

(a) As the angle of incidence increases, the angle of deviation decreases first and reaches to a minimum value (
