A thin prism of angle 6.0^@, omega=0.07 ...

A thin prism of angle `6.0^@, omega=0.07 and mu_y=1.50` is combined with another thin prism having `omega = 0.08 and mu_y = 1.60`. 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).
