Three light rays, red (R) green (G) and blue (B) are incident on a right angled prism AB C 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 of ray will emerge out of face AC? Justify your answer. Trace the path of these rays after passing through face
