In Young's double slit experiment, the ratio of intensities at two points on a screen when waves from the two slits have a path difference of zero and 4 is [ 0^ = 90^ =1, 0^ = 90^ =0 ]

Options

  1. A2: 1
  2. B3: 1
  3. C2: 3
  4. D3: 2

Correct answer

A. 2: 1

Step-by-step solution

I=4 I₀ ² 2 = 2 4 = 2 2 = 4 1 I₀ =4 ² 4 = 4 2 =2: 1
