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 combinatino when white light goes through it. Refractive indices for red, yellow, and violet light are 1.541, 1.517 and 1.523, repectively, for crown flass and 1.613, 1.620 and 1.632 for flint glass.
