An unpolarized beam of light is incident on a glass surface at an angle of incidence equal to the polarizing angle of the glass. Read the following statements:
(i) The reflected beam is completely polarized
(ii) The refracted beam is partially polarized
(iii) The angle between the reflected and the refracted beam is

90^{\circ}

.
Which of the above statements is/are true?

View answer and explanation

Correct option: C

(i) and (iii)

Option C ((i) and (iii)) is correct because at the polarizing angle, the reflected light is completely polarized and the angle between reflected and refracted rays is 90 degrees.
