After passing through a polariser a linearly polarised light of intensity I is incident on an analyser making an angle of 30^ with that of the polariser. The intensity of light emitted from the analyser will be :

Options

  1. AI 2
  2. BI 3
  3. C3 I 4
  4. D2 I 4

Correct answer

C. 3 I 4

Step-by-step solution

As per Malus law, I = I ₀ ^2 , where symbols have their usual meanings. aligned & I^ =I ^2 30^ & I^ =I ( 3 2 )^2 & I^ = 3 I 4 aligned
