Group Velocity Calculator

Posted by Dinesh on

The 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:

vg(?) = ?? / ?k

where,
? - is the wave's angular frequency (usually expressed in radians per second)
k - is the angular wavenumber (usually expressed in radians per meter)
vg(?) - group velocity
