What is wave velocity and particle velocity?

Wave velocity is a wave property, which may refer to:

phase velocity, the velocity at which a wave phase propagates at a certain frequency

pulse wave velocity, the velocity at which a pulse travels through a medium, usually applied to arteries as a measure of arterial stiffness

group velocity, the propagation velocity for the envelope of wave groups and often of wave energy, different from the phase velocity for dispersive waves

signal velocity or information velocity, which is the velocity at which a wave carries information

front velocity, the velocity at which the first rise of a pulse above zero moves forward
