Two beams of light having intensities I and 4I, interfere to produce a fringe pattern on a screen. The phase difference between the beams is 
, at a point A and 
, at a point B. The difference between the resultant intensities at A and B is
Text Solution
Verified by ExpertsThe correct answer is:
B
41
Resultant intensity due to superposition of two waves on the screen is given as
Here, I 1 = I and I 2 = 4I
At point A, 
At point B,
