The two light beams having intensities I and 9I interfere to produce a fringe pattern on a screen. The phase difference between the beams is π/2 at point P and π at point Q. Then the difference between the resultant intensities at P and Q will be :

Multiple Choice Options

  • A 2 I
  • B 6 I
  • C 5 I
  • D 7 I

Step-by-Step Verified Solution

IP=I+9I+2I×9Icos⁡π2=10I

IQ=I+9I+2I×9Icos⁡π=4I

So, IP−IQ=6I
