Question

A thin prism of angle 5.0°, 0 = 0.07 and My = 1.30 is combined with another thin prism having
o' = 0.08 and uy = 1.50. The combination produces no deviation in the mean ray. (a) Find the angle of
the second prism. (b) Find the net angular dispersion produced by the combination when a beam of
white light passes through it. (c) If the prisms are similarly directed, what will be the deviation in the
mean ray? (d) Find the angular dispersion in the situation described in (c).​
