fata. 1  definite singular nominative form of fatÄ. 2  definite singular accusative form of fatÄ.
1. Once a wave has been generated its speed may change, but its period does not as this characteristic is determined by the generating force. 2. Deep-water waves (waves of oscillation) a. Deep-water waves occur where the water is deeper than 1/2 the wavelength of the waves. b. In deep water the velocity of a wave is a function of wavelength. c. Waves are created in storm centers or by the steady winds of the westerlies and trades.
Water waves, in this context, are waves propagating on the water surface, and forced by gravity and surface tension. As a result, water with a free surface is generally considered to be a dispersive medium. Surface gravity waves, moving under the forcing by gravity, propagate faster for increasing wavelength.
