The speed of propagation of a sine wave or a sinusoidal component of a complex wave, equal to the product of its wavelength and frequency is known as phase velocity.
The speed at which the energy of a wave travels is known as group velocity.
The speed at which the energy of a wave travels is known as group velocity.

Answer:
Phase Velocity is the speed of propagation of a sine wave or sinusoidal component of a complex wave, equal to the product of its wavelength and frequency
Group velocity on the other hand is the speed at which the energy of a wave travels.
