The angle between the axes of a polariser and an analyser is 45^ . If the intensity of the unpolarized light incident on the polariser is 1 , then the intensity of the light emerged from the analyser is

Options

  1. A2 I
  2. BI 2
  3. CI
  4. DI 4

Correct answer

D. I 4

Step-by-step solution

The intensity of light after passing through polariser is I ₁= I 2 The intensity of light after passing through analyses is I₂=I₁ ^2 = I 2 ^2 45^ = I 2 ( 1 2 )^2= I 4
