An unpolarised beam of intensity

2{a^2}

passes through a thin Polaroid. Assuming zero absorption in the Polaroid, the intensity of emergent plane polarized light is

View answer and explanation

Correct option: B

{a^2}

Option B (

{a^2}

) is correct because when unpolarized light passes through a polarizer, its intensity is reduced by half, assuming zero absorption.
