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

Options

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

Correct answer

A. K 4

Step-by-step solution

The intensity is given by I =4 I ₀ ^2 2 Maximum intensity K =4 I ₀ when =0 When path difference is 3 , = 2 3 I = K ^2 3 = K ( 1 2 )^2= K 4
