Assertion: The phase difference between any two poitns on a wave front is zero.

Reason: Light from the source reaches every point ofthe wave front at the same time.

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 a wavefront is defined as a surface of constant phase, reached at the same time by light from the source.
