Summary
DescriptionWave disp.gif
English: Frequency dispersion of surface gravity waves on deep water. The superposition of three wave components, with respectively 22, 25 and 29 wavelengths fitting in a horizontal domain of 2,000 meter length, is shown. The wave amplitudes of the components are respectively 1, 2 and 1 meter. The differences in wavelength and phase speed of the components results in a changing pattern of wave groups, due to amplification where the components are in phase, and reduction where they are in anti-phase.
