In Young's double slit experiment if the slit widths are in the ratio 1: 9 . The ratio of the intensity at minima to that at maxima will be

Options

  1. A1
  2. B1 / 9
  3. C1,4
  4. D1 / 3

Correct answer

C. 1,4

Step-by-step solution

Amplitude of the superimposing waves are array l a₁ a₂ = ( 1 9 )^ 1 / 2 = 1 3 I_ minima I_ maxima = (a₁-a₂ )² (a₁+a₂ )² = 1 4 array
