In a direct vision spectroscope there are two flint glass prisms each of angle `5^(@)` and dispersive power 0.36 and two crown glass prisms of dispersive power 0.24. Calculate the angle of each crown glass prism and the net dispersion produced by the system of prisms. `(mu_("crown")=1.5 and mu_("flint")=1.68)`
