When a light ray incidents on the surface of a medium, the reflected ray is completely polarized. Then the angle between reflected and refracted rays is
$45^{\circ}$
$90^{\circ}$
$120^{\circ}$
$180^{\circ}$
Solution
According to Brewester's law if the reflected ray is completely polarized, then the reflected and refracted ray is perpendicular to each other.
Thus, $\theta=90^{\circ}$
