Question

A prism of refracting angle $30\°$ is coated with a thin film of transparent material of refractive index 2.2 on face AC as shown in the figure. A light of wavelength 6600 $\AA$ is incident on face AB such that angle of incidence is $30\°$. Find, (a) the angle of emergence and (b) the minimum value of thickness of the coated film on the face AC for which the light emerging from the face has maximum intensity. [Given refractive index of the material of the prism is $\sqrt{3}$.]
