Three light rays red (R), green (G) and blue (B) 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 time three which colour ray will emerge out of face 'ac' ? Justify your answer. Trace the path of these rays after passing through face 'ab'

Three rays of light, namely red (R), green (G) and blue (B) are incident on the face PQ of a right angled prism PQR as showns in the figure. The refractive indices of the material of the prism for red green and blue wavelength are 1.27, 1.42 and 1.49 respectively. The colour of the ray(s) emerging out of the face PR is:
