Phase velocity v → p is the speed and direction at which the phase of a wave propagates through space. If you were to throw a rock in a body of water and track a point on one of the ripples, you would be observing the phase velocity of the wave.

What is phase velocity and explain it?
The phase velocity of a wave is the rate at which the wave propagates in any medium. This is the velocity at which the phase of any one frequency component of the wave travels. For such a component, any given phase of the wave (for example, the crest) will appear to travel at the phase velocity.
What is phase velocity formula?
It is related to the wavenumber k and the (angular) optical frequency ω: In vacuum, the phase velocity is c = 299 792 458 m/s, independent of the optical frequency, and equals the group velocity.
What is an example of wave velocity?
If the crest of an ocean wave moves a distance of 20 meters in 10 seconds, then the speed of the ocean wave is 2.0 m/s. On the other hand, if the crest of an ocean wave moves a distance of 25 meters in 10 seconds (the same amount of time), then the speed of this ocean wave is 2.5 m/s.
What is the phase velocity and wave velocity?
Waves can be in a group and such groups are called wave packets, so the velocity with which a wave packet travels is called group velocity. The velocity with which the phase of a wave travels is called phase velocity.
