Linear dispersion relation
NettetIn this case the dispersion relation allows for two modes: a barotropic mode where the free surface amplitude is large compared with the amplitude of the interfacial … The full linear dispersion relation was first found by Pierre-Simon Laplace, although there were some errors in his solution for the linear wave problem. The complete theory for linear water waves, including dispersion, was derived by George Biddell Airy and published in about 1840. A similar equation was also found by Philip Kelland at around the same time (but making some mistakes in his derivation of the wave theory).

Nettet14. sep. 2024 · 1 Answer. So the idea is that different plane waves will travel with different speeds v = λ f = k − 1 ω ( k). A wave packet made of multiple of these would then be expected to disperse as one wave packet overtakes another. Worth remembering that dispersion is not diffusion. The most common example is a Gaussian wave packet …
