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'.

The bottom of a container is a 4.0 cm thick glass (mu=1.5) slab. The container contains two immiscible liquids A and B of depths 6.0 and 8.0 cm respectively. What is the apparent position of a scratch on the outer surface on the bottom of the glass slab, when viewed through the container? Refractive indices of A and B are 1.4 and 1.3 respectively.

Two beams of red and violet colours re mde to pass separaterly through a prism (angle of prism is 60^@ ).In the position of minimum deviation,the angle of refraction will be

Prism A prism is a portion of transparent refracting medium bounded by two plane surfaces inclined to each other at a certain angle, and the angle between the refracting faces is called angle of the prism denoted by A. The deviation produced by the prism is maximum for violet (delta_v) and minimum for red (delta_r) colour. Mean refractive index of material for yellow colour is:
