Unpolarised light incident on transparent glass at incident angle

60^{\circ}

. If reflected ray is completely polarised, then angle of refraction is

View answer and explanation

Correct option: C

30^{\circ}

Option C (

30^{\circ}

) is correct because, according to Brewster's law, the angle of incidence plus the angle of refraction equals 90 degrees when the reflected ray is completely polarized.
