An unpolarized light beam travelling in air is incident on a medium of refractive index 1.73 at Brewster’s angle. Then

An unpolarized light beam travelling in air is incident on a medium of refractive index 1.73 at Brewster’s angle. Then 

(1) Reflected light is completely polarized and the angle of reflection is close to 60° 

(2) Reflected light is partially polarized and the angle of reflection is close to 30° 

(3) Both reflected and transmitted light are perfectly polarized with angles of reflection and refraction close to 60° and 30°, respectively 

(4) Transmitted light is completely polarized with angle of refraction close to 30°          (NEET-2025)
