White light is pased through a glass prism of angle `5^@`.If the refractive indices for red and blue colours are 1.641 adn 1.659 respectively ,calculate the angle of disperson betwen these colours.

The refractive indiceis of crown and flint glasses for blue and red rays are 1.523 ,1.513 adn 1.773,1.743 rspectively.Calculate the dispersive powers of teh two glasses.

Find the angle of dispersion between the red and violet colours produced by a flint glass prism of refracting angle 60^@ .Refrative indices of the prism for red and violet colours are 1.622 and 1.663 respectively.

Three light rays red, green and blue are incident on a right angled prism 'abc' at face 'ab'. The refractive indices of the material of the prism for red, green and blue wavelengths are 1.39, 1.44 and 1.47 respectively. Out of the three which colour ray will emerge out of face 'ac'? justify your answer. Trace the out of the face 'ac'? Justify your answer. Trace the path of these rays after passing through face 'ab'.

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?
