A crown glass prism of angle `5^@` is to be combined with a flint glass prism in such a way that the mean ray passes undeviated. Find (a) the angle of the flint glass prism needed and (b) the angular dispersion produced by the combination when white light goes through it. Refractive indices for red, yellow and viloet light are 1.514, 1.517 and 1.523 respectively for crown glass and 1.613 1.620 and 1.632 for flint glass.

To solve the problem step by step, we will break it down into two parts as per the question: ### Part (a): Finding the angle of the Flint Glass Prism 1. **Understanding the Condition for Undeviated Ray**: When two prisms are combined such that the mean ray passes undeviated, the deviation produced by the crown glass prism must equal the deviation produced by the flint glass prism. This can be expressed mathematically as: \[ \Delta_1 = \Delta_2 ...
