MHT CET Physics question

Which of the following statement is true when wave is reflected from denser medium:

(A)wave velocity reverses its direction
(B)particle velocity reverses its direction
(C)Both a & b are trueCorrect
(D)It depends upon nature of wave.

Answer: (C)

Solution

On reflection the wave travels back, so wave velocity reverses, and because the displacement suffers a phase change of at the denser boundary the particle
