A crown glass prism of angle 5 is to be combined with a flint 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

A = 60 n = root 7/3. Find the minimum possible angle of incidence For a prism so that the light ray is refracted from the second surface. Also find delta max.
