The phase velocity $(v_p)$ of travelling wave is |
$v_p=\frac{ω}{k}$ $v_p=\frac{dω}{dk}$ $v_p=c$ $v_p=\frac{c}{v_g}$ |
$v_p=\frac{ω}{k}$ |
The phase velocity of a wave is rate at which the phase of the wave propagates in space. This is the speed at which the phase of any one frequency component of the wave travels. For such a component, any given phase of the wave will appear to travel at the phase velocity. It is given in terms of wave’s angular velocity ω and wave |
