property, which may refer to:
- phase velocity
The phase velocity of a wave is the rate at which the phase of the wave propagates in space. This is the speed at which the phase of any one frequency component of the wave travels. For such a component, any given phase of the wave will appear to travel at the phase velocity...
, the velocity at which a wave phase propagates at a certain frequency
- group velocity
The group velocity of a wave is the velocity with which the overall shape of the wave's amplitudes — known as the modulation or envelope of the wave — propagates through space....
, 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 signal velocity is the speed at which a wave carries information. It describes how quickly a message can be communicated between two separated parties...
or information velocity, which is the velocity at which a wave carries information
- front velocity
In physics, front velocity is the speed at which the first rise of a pulse above zero moves forward.In mathematics, it is also used to describe the velocity of a possibly propagating front in the solution of hyperbolic partial differential equation....
