Formula of phase velocity
WebThe velocity is the time derivative of the position, which is the slope at a point on the graph of position versus time. The velocity is not v = 0.00 m/s v = 0.00 m/s at time t = 0.00 s t … WebThat is, to within a phase factor of unit modulus the waveform f(x,t) is a function of a single variable,x− (dω(k0)/dk)t, and so can be said to propagate with the group velocity, vgroup = dω(k0) dk. (6) As argued above, the wave energy propagates with this velocity as well.
