Vedclass · Answer

(B) According to Brewster's Law,when the reflected ray is completely polarized,the angle of incidence is equal to the Brewster's angle $(i_{p})$.Given $i_{p} = 60^{\circ}$.The refractive index $\mu$ is given by $\mu = 	an(i_{p})$.$\mu = 	an(60^{\circ}) = \sqrt{3}$.The velocity of light in a medium is given by $v = \frac{c}{\mu}$,where $c$ is the speed of light in vacuum $(3 	imes 10^{8} \, m/s)$.$v = \frac{3 	imes 10^{8}}{\sqrt{3}} = \sqrt{3} 	imes 10^{8} \, m/s$.

When the angle of incidence is $60^{\circ}$ on the surface of a glass slab,it is found that the reflected ray is completely polarized. The velocity of light in glass is
