Statement I: Two point coherent sources ...

Statement I: Two point coherent sources of light `S_(1)` and `S_(2)` are placed on a line as shown in figure. P and Q are two points on that line. If at point P maximum intensity is observed, then maximum intensity should also be observed at Q.

Statement II: In figure the distance `|S_(1) P - S_(2) P|` is equal to distance `|S_(1) Q - S_(2) Q|`.

A

Statement I is True, statement II is True, Statement II is a correct explanation for Statement I.

B

Statement I is Ture, Statement II is Ture, Statement II is NOT a correct explanation for Statement I.

C

Statement I is True, Statement II is False.

D

Statement I is False, Statement II is True.

Text Solution

Verified by Experts

The correct Answer is:
a
If maximum intensity is observed at P, the for maximum intensity to to be also observed at Q, `S_(1)` and `S_(2)` must have phase difference of `2m pi` (where m is an integer).
