Wave velocity

From Wikipedia, the free encyclopedia

Wave velocity may refer to:

  • Phase velocity, the velocity at which a wave phase propagates
  • 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
