Sea can cause individual (unexpected) rogue waves much higher than normal. Most waves are less than high and it is not unusual for strong storms to double or triple that height; offshore construction such as wind farms and oil platforms use metocean statistics from measurements in computing the wave forces (due to for instance the hundred-year wave) they are designed against. Rogue waves, however, have been documented at heights above . The top of a wave is known as the crest, the lowest point between waves is the trough and the distance between the crests is the wavelength. The wave is
Wave equation the wave, which is reflected by a dispersion relation where "ω" is the angular frequency and k is the wavevector describing plane wave solutions. For light waves, the dispersion relation is "ω" = ±"c" |k|, but in general, the constant speed "c" gets replaced by a variable phase velocity: Wave equation The wave equation is an important second-order linear partial differential equation for the description of waves—as they occur in classical physics—such as mechanical waves (e.g. water waves, sound waves and seismic waves) or light waves. It arises in fields like acoustics, electromagnetics, and fluid dynamics. Historically, the problem of
