Brewster's angle for a glass of refractive index $\sqrt{3}$ (relative to air) is:

Brewster's law: $\tan i_B = \mu$. With $\mu = \sqrt{3}$, $\tan i_B = \sqrt{3} \Rightarrow i_B = 60^\circ$. At this angle the reflected light is completely plane-polarised, with the electric field perpendicular to the plane of incidence.
