The light waves from two coherent sources have same intensity I 1 = I 2 = I 0 . In interference pattern the intensity of light at minima is zero. What will be the intensity of light at maxima?

Options

  1. AI 0
  2. B2 I 0
  3. C4 I 0
  4. D5 I 0

Correct answer

C. 4 I 0

Step-by-step solution

I m i n i m u m   = 0 I 1 - I 2 2 = 0 ⇒    I 1 = I 2 I max = I 1 + I 2 2 = 4 I 0
