When unpolarized light is incident at an angle of $60^\circ$ on a transparent medium from air, the reflected ray is completely polarized. The angle of refraction in the medium is
Answer: (A) $30^\circ$
$60^\circ$ is the Brewster angle, at which the reflected and refracted rays are perpendicular: $r = 90^\circ - 60^\circ = 30^\circ$.
