Three rays of light -red(R),green(G) and blue(B)-are incident on the face AB of a rigth-angled prism ABC as shown in Fig.3.27. The refractie indices of the material of the prism for red,green and blue wavelengths are 1.39,1.44 adn 1.47 respectively. Trace the path of the rays thruogh the prism.How will the situation change,if these rays were incident normally on one of the faces of an equilateral prism?
