Find the dispersion produced by a thin prism of 18^(@) having refractive index for red ligh =1.56 and for violet light =1.68 .

We have to combine a crown glass prism of angle 4^(@) with a flint glass prism in such a way that the mean ray passes undeviated, find (i) the angle of the flint glass prism needed and (i) the angular dispersion produced by the combination when white light goes through it. Refractive indices for red, yellow and violet light are 1.514, 1.517 and 1.523 respectively for crown glass and 1.613, 1.620 and 1.632 for flint glass.

Red and violet light have

Assertion (A): The light of violet colour deviates the most and the light of red colour the least, while passing through a prim. Reason (R):The refractive index in highest for red light and lowest for the violet light.

How is refracted most by a prism : red light or violet light ? Explain why ?

In a certain spectrum produced by a glass prism of dispersive power 0.0305, it is found that the refractive index for the red ray is 1.645. and that for the violet ray is 1.665 . What is the refractive index for the yellow ray?

Calculate the dispersion and deviation ( mean) produced by a flint glass prism placed in the position of minimum deviation with respect to the mean colour. The angle of prism is 60^(@) . Also calculate the dispersive power of the prism. Index of refraction of flint glass for blue light=0.667 and that for the red light =1.643.
