Physics - Wave Optics Question with Solution | TestHub

According to Brewster's law, reflected light is plane polarised if unpolarised light falls at the interface of air and medium at an angle ${\mathrm{i}}_{\mathrm{p}}$ called polarising angle then $\mu =\tan {\mathrm{i}}_{\mathrm{p}}\Rightarrow \mu (\text{ glass })=\tan 60^{\circ }=\sqrt{3}$
