Question:
A thin prism of crown glass $\left(\mu_{r}=1.515, \mu_{v}=1.525\right.$ ) and a thin prism of flint glass ( $\mu_{r}=1.612, \mu_{v}=1.632$ ) are placed in contact with each other. Their reflecting angles are $5.0^{\circ}$ each and are similarly directed. Calculated the angular dispersion produced by the combination.
Solution:
