Assertion: No interference pattern is detected when two coherent sources are very close to each other. (i.e. separation almost zero).

Reason: The fringe width is inversely proportional to the distance between the two slits.

View answer and explanation

Correct option: A

Both Assertion and Reason are true and Reason is the correct explanation of Assertion

Option A (Both Assertion and Reason are true and Reason is the correct explanation of Assertion) is correct because when the sources are very close, the fringe width becomes very large, making it difficult to observe a distinct interference pattern.
