When unpolarised light is passed through crossed polaroids, then light passing through first polaroid

Options

  1. Aalso passes through second polaroid.
  2. Bpartially passes through second polaroid.
  3. Cis blocked by second polaroid.
  4. Dpasses with greater intensity.

Correct answer

C. is blocked by second polaroid.

Step-by-step solution

Intensity passed by the second polaroid is given by I=I₀ ² when =90^ , I=0
