Assertion : Two point coherent sources of light S_1 and S_2 are...
Assertion : Two point coherent sources of light are placed on a line as shown. are two points on that line. If at point maximum intensity is observed then maximum intensity should also be observed at Q.
Reason : In the figure of assertion the distance is equal to distance \left|S_2 Q-S_1 Q\right|.
Reason : In the figure of assertion the distance is equal to distance \left|S_2 Q-S_1 Q\right|.
Options
- AIf both assertion and reason are true and reason is the correct explanation of assertion.
- BIf both assertion and reason are true but reason is not the correct explanation of assertion.
- CIf assertion is true but reason is false.
- DIf both assertion and reason are false.
Correct answer
B. If both assertion and reason are true but reason is not the correct explanation of assertion.
Step-by-step solution
If maximum intensity is observed at then for maximum intensity to be also observed at and must have phase difference of (where is an integer).
