The dispersion equation for gravity waves c= √(gL/2π) indicates that waves of longer wavelength (L) propagate faster than those of shorter wavelengths. Compared to that, capillary waves (only forced by surface tension) travel faster for shorter wavelengths.\begin… text/html 2014-07-01T10:04:06+00:00 Anonymous (anonymous@undisclosed.example.com) https://oceanwiki.ethz.ch/doku.php?id=lecture12:internalwaves&rev=1404209046&do=diff Internal Waves Authors: Daniela König, Claudia Erhart Introduction Internal waves are gravity waves which occur at an interface between two layers with different densities (different temperature and/or salinity), whereas surface waves are external gravity waves. These waves result where there is a strong increase in density with depth. Internal waves travel less fast than surface waves. Also less energy is needed to displace the interface from its equilibrium position, and oscillations are … text/html 2015-02-09T14:22:51+00:00 Anonymous (anonymous@undisclosed.example.com) https://oceanwiki.ethz.ch/doku.php?id=lecture12:kelvinwave&rev=1423491771&do=diff Kelvin Waves Author: Elisa Lovecchio Kelvin waves are large-scale waves that propagate along boundaries.
