Show that deviaetion produced by a thin angled prism is `Omega = (mu -1)A`

Show that v=r omega .

Prism A prism is a portion of transparent refracting medium bounded by two plane surfaces inclined to each other at a certain angle, and the angle between the refracting faces is called angle of the prism denoted by A. The deviation produced by the prism is maximum for violet (delta_v) and minimum for red (delta_r) colour. Dispersive power (omega) of the prism is given by
