Light waves from two coherent sources arrive at two points on a screen with path difference of zero and / 2 . The ratio of the intensities at the points is

Options

  1. Atwo : one
  2. Bone:two
  3. Cone: one
  4. Dinfinity: one

Correct answer

D. infinity: one

Step-by-step solution

When path difference is zero, the resultant intensity I=4 I₀ , where I₀ is the intensity of the individual waves. When the path difference is 2 , the intensity I^ =0 I I^ = 4 I₀ 0 =
