Wave 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, the velocity at which a wave carries information
• front velocity, the velocity at which the first rise of a pulse above zero moves forward
