... groups of waves comprising a limited range of frequencies travel at a velocity called the group velocity, different from the phase velocity. 3, record 1, English, - group%20velocity
Record number: 1, Textual support number: 2 CONT
Group velocity differs from the steady state velocity of a sinusoidal wave only when the latter varies with frequency; the group velocity as thus defined is equal to the first derivative of the frequency with respect to the reciprocal of the wavelength. 4, record 1, English, - group%20velocity

La velocidad de grupo difiere de la velocidad de fase en un medio en que ésta varía en función de la frecuencia. 1, record 1, Spanish, - velocidad%20de%20grupo
