(A)Reflected and refracted rays are completely polarized with their planes of polarisation parallel to each other
(B)Reflected and refracted rays are completely polarised with their planes of polarisation perpendicular to each other
(C)Reflected light is plane polarised but transmitted light is partially polarisedCorrect
(D)Reflected light is partially polarised but refracted light is plane polarised

Answer: (C)

Solution

At Brewster's angle the reflected light is completely plane polarised while the refracted
