A) 0 : 1 : 4
B) 4 : 1 : 0
C) 0 : 1 : 2
D) 2 : 1 : 0
Correct Answer: D
Solution :
Since P is ahead of Q by 90o and path difference between P and Q is \[\lambda /4\].Therefore at A, phase difference is zero, so intensity is 4I. At C it is zero and at B, the phase difference is 90o, so intensity is 2I.You need to login to perform this action.
