An unpolarized light beam travelling in air is incident on a medium of refractive index 1.73 at Brewster's angle. Then-
(1). transmitted light is completely polarized with angle of refraction close to \(30^\circ\)
(2). reflected light is completely polarized and the angle of reflection is close to \(60^\circ\)
(3). reflected light is partially polarized and the angle of reflection is close to \(30^\circ\)
(4). both reflected and transmitted light are perfectly polarized with angles of reflection and refraction close to \(60^\circ\) and \(30^\circ\), respectively.
