In each of the following questions read the two statements and choose if

Statement-1. On reflection from a rigid boundary (denser medium), there is a complete reversal of phase.

Statement-2. This is because on reflection at a denser medium, both the particle velocity and wave velocity are reversed in sign.
(A) Statement-1 is true ; Statement-2 is true \( ; \) Statement- 2 is correct explanation of Statement- \( 1 . \)
(B) Statement-1 is true ; Statement-2 is true;
Statement-2 is not a correct explanation of Statement-1.
