Two monochromatic beams of intensities I and 4I respectively are superposed to form a steady interference pattern. The maximum and minimum intensities in the pattern are

Options

  1. A4 I and I
  2. B9I and 3 I
  3. C5 I and 3 I
  4. D9I and I

Correct answer

D. 9I and I

Step-by-step solution

aligned & I_ =I+4 I+2 (I)(4 I) =9 I & I_ =I+4 I-2 (I)(4 I) =I aligned
