Light is incident on a polarizer with intensity I₀ . A second prism called analyzer is kept at a angle of 15^ , from the first polarizer then the intensity of final emergent light will be

Options

  1. AI₀( 2 -1)
  2. BI₀( 3 -1)
  3. CI₀ 4 (2+ 3 )
  4. DI₀ 4 (2- 3 )

Correct answer

C. I₀ 4 (2+ 3 )

Step-by-step solution

Intensity of final emergent light aligned & I= I₀ 2 ^2 (15^ )== I₀ 4 [1+ (30^ ) ] & = I₀ 4 [1+ 3 2 ]= I₀ 4 [2+ 3 ] aligned
