RE-NEET 2024 Physics Polarization MCQ Question

Type: MCQ-numerical-Medium-Class 12

A beam of unpolarized light of intensity I₀ is passed through a polaroid A, then through another polaroid B, oriented at 60° and finally through another polaroid C, oriented at 45° relative to B as shown. The intensity of emergent light is:

Question diagram
A

I016\frac{I_0}{16}

B

I04\frac{I_0}{4}

C

I02\frac{I_0}{2}

D

I032\frac{I_0}{32}

Correct Answer

Option A

Detailed Explanation

The intensity of light after passing through each polaroid is calculated using Malus's law. After passing through all three polaroids, the intensity is I016\frac{I_0}{16}.
