Assertion: On reflection from a rigid boundary there takes place a complete reversal of phase.
Reason: On reflection from a denser medium, both the
P
particle velocity and wave velocity are reversed in sign.
(1) Assertion is True, Reason is True; Reason is correct explanation for Assertion
(2) Assertion is True, Reason is True; Reason is not correct explanation for Assertion
(3) Assertion is True, Reason is False
(4) If both Assertion and Reason are False
