Question
What is the difference between wave velocity and particle velocity?
Solution
Wave velocity:
Wave velocity is the velocity with which progressive wave front travels forward. It is constant throughout the media if the media is homogenous and given by,
v = v λ.
Particle velocity:
Particle velocity is the velocity with which particles vibrate during the wave propagation. The particle velocity is changing and given by,
v = rω cos(ωt – kx).
