long gravity wave

…the waves are known as long gravity waves, and their wavelength is directly proportional to their period. The deeper the water, the faster they travel. For capillary waves, shorter wavelengths travel faster than longer ones.

…of this kind are called long gravity waves or shallow-water waves), and C² = gL/2π when the wavelength is less than two times the water depth (such waves are called short waves or deepwater waves). For waves with lengths between 2 and 20 times the water depth, the wave speed…
