Assertion: In Young's double slit experiment interference pattern disappears when one of the lits is closed.

Reason: Interference occuts due to super imposition of light waves from two coherent sources.

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 interference requires two coherent sources, and closing one slit eliminates the second source, thus stopping the interference pattern.
