Summary
| Description |
English: The phase velocity cp (blue line) and group velocity cg (red line) as a function of water depth h, for surface gravity waves of constant period according to Airy wave theory. Quantities have been made dimensionless using the gravitational acceleration g and period T. The deep-water wavelength is L0 = g/(2π)T2 and the deep-water phase speed is c0 = L0/T. The grey line corresponds with the shallow-water limit cp =cg = √(gh). The phase velocity cp is related to the wavelength L through cp = L/T. Consequently, for fixed period T, L/L0 varies identical to cp/c0 with depth changes. |
