Define dispersive power of a prism.

Calculate the dispersion and deviation ( mean) produced by a flint glass prism placed in the position of minimum deviation with respect to the mean colour. The angle of prism is 60^(@) . Also calculate the dispersive power of the prism. Index of refraction of flint glass for blue light=0.667 and that for the red light =1.643.

A glass prism is held in water. How is its angle of minimum deviation affected?
