Phase difference between two overlapping waves to produce a bright band is .

Assertion: Phase difference between two overlapping waves to produce a bright band is $2\pi, 4\pi, 6\pi, 8\pi, \dots, 2n\pi$.

Reason: When crest of one wave falls on crest of another wave, amplitude of the resulting wave decreases.

• (a)Both Assertion and Reason are true and Reason is the correct explanation for Assertion.
• (b)Both Assertion and Reason are true but Reason is not the correct explanation for Assertion.
• (c)Assertion is true and Reason is false.
• (d)Both Assertion and Reason are false.
