Waves on deep water with surface tension T and density p are governed by the dispersion relation: ² = gk +k³, where w is the angular frequency of the wave, k the wavenumber, and g is a constant. Calculate: 1- The phase and group velocities of the waves. 2- The critical wavenumber, ke, when the phase speed of the wave reaches a minimum.
