In Young's double slit experiment using monochromatic light of wavelength ' ', the intensity of light at a point on the screen where path difference ' ' is K units. The intensity of light at a point where the path difference is 6 is [ 6 = 3 = 3 2 ]

Options

  1. AK
  2. B3 ~K 4
  3. CK 2
  4. DK 4

Correct answer

B. 3 ~K 4

Step-by-step solution

The intensity is given by I=4 I₀ ^2 2 Maximum intensity K =4 I ₀ when =0 when path difference is 6 , aligned & = 2 path difference = 3 & I=K ^2 ( 6 )=K ( 1 4 )= 3 K 4 aligned ...[From(i) and (ii)]
