An unpolarised beam of light is incident on a group of four polarising sheets which are arranged in such a way that the characteristic direction of each polarising sheet makes an angle of

30^{\circ}

with that of the preceding sheet.The percentage of incident light transmitted by the first polariser will be

View answer and explanation

Correct option: B

50 \%

Option B (50 %) is correct because the first polariser reduces the intensity of unpolarised light by half.
