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.
The speed of a deep-water wave may also be approximated by: where g is the acceleration due to gravity, 9.8 meters (32 feet) per second squared. Because g and Ï (3.14) are constants, the equation can be reduced to: when C is measured in meters per second and L in meters.
