# Group Velocity Calculator

Posted by Dinesh onThe group velocity of a wave is the velocity with which the overall shape of the waves' amplitudes known as the modulation or envelope of the wave propagates through space.

### Formula:

v_{g}(?) = ?? / ?k

? - is the wave's angular frequency (usually expressed in radians per second)

k - is the angular wavenumber (usually expressed in radians per meter)

v

_{g}(?) - group velocity
