Refractive index of glass, $\mu=1.5$
Brewster angle = $\theta$
Brewster angle is related to refractive index as:
$\text{tan}\theta=\mu$
$\theta=\text{tan}^{-1}(1.5)=56.31^\circ$
Therefore, the Brewster angle for air to glass transition is 56.31°.

    Unpolarised light is passed through a polaroid $P_1$. When this polarised beam passes through another polaroid $P_2$ and if the pass axis of $\mathrm{P}_2$ makes angle $\theta$ with the pass axis of $\mathrm{P}_1$, then write the expression for the polarised beam passing through $\mathrm{P}_2$. Draw a plot showing the variation of intensity when $\theta$ varies from 0 to $2 \pi$.
