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

Answer: (A)

Solution

At a rigid boundary the displacement must remain zero, so the reflected wave is inverted (phase change of ): the particle velocity and the wave velocity of the reflected wave are
