Problem 5.190

Plane-polarized light of wavelength 0.59 \mum falls on a trihedral quartz prism $P$ (Fig. 5.34 ) with refracting angle $\Theta=$ $=30^{\circ}$. Inside the prism light propagates along the optical axis whose direction is shown by hatching. Behind the Polaroid Pol an interference pattern of bright and dark fringes of width $\Delta x$ $=15.0 \mathrm{~mm}$ is observed. Find the specific rotation constant of quartz and the distribution of intensity of light behind the Polaroid.
