Question

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

Accepted Answer

C. $60^\circ$

**Brewster's law:** $	an i_B = \mu$.
With $\mu = \sqrt{3}$, $	an 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.

Answer

$30^\circ$

Answer

$45^\circ$

Answer

$90^\circ$
