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?

A beam of light consisting of red, green and blue and is incident on a right angled prism. The refractive index of the material of the prism for the above red, green and blue wavelengths are 1.39, 1.44 and 1.47 respectively. The prism will : .

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'.

Two monochromatic rays of light are incident normally on the face AB of an isosceles right-angled prism ABC.The refractive indices of the glass prism for the two rays 1 and 2 are respectively 1.35 and 1.45[Fig.2.76]Trace the path of these rays after entering through the prism .
