Wave characteristics, английский
The kinetic energy of waves is tremendous. a relatively small 1.22 meter (4 foot) high wave striking a coast at 10 second intervals expends more than 26,000 kilowatts (35,000 horsepower) per mile of beach, meaning that the energy along a 56-mile stretch is equal to the power generated by hoover dam (bowditch 1995 edition). waves are defined by five characteristics: • height—the vertical distance from trough to crest; • length—the horizontal distance between crests; • period—the time interval between successive crests as they pass a specific point; • velocity—the speed of the wave-form’s forward movement (which seldom exceeds 25 knots = 29 mph = 46 km/h); • surface drift—the actual advance of the water (usually about one-percent of the wave velocity). the highest regular sinusoidal ocean wave (as opposed to an irregular rogue wave) was reliably measured by officers of 16,800 ton fleet oiler uss ramapo in the north pacific on 7th february 1933. following an extraordinary week-long storm that stretched from new york city to the coast of asia, powerful 60-knot (70 mph; 110 km/h) winds crossing thousands of kilometers of unobstructed ocean had produced mountainous waves. by triangulation based on the ship’s superstructure, its officers calculated a height of 34 meters (112 feet) from trough to crest. the crest-tocrest length was calculated as 342 meters which explains why relatively short ramapo (146 meters) was able to ride the waves without the severe structural distress which would have afflicted a longer vessel. see also measurement of wind and wave, wave formation, and wave motion.
Wave combination, английский
There are statistics that give some support to the old rule of thumb about every seventh wave being a big one. being caused by winds of varying strength, waves are of varying sizes and travel at different speeds. over the open sea, faster moving waves catch up with slower ones, combining to produce a larger wave. moreover, wind waves are often superimposed on swell and the combination can be critically important to cargo vessels, causing deck cargo to be washed overboard or bulk cargo to shift dangerously.
Wave crest, английский
The highest part of a wave.
Wave crest / trough, английский

- For light waves or sound waves, the distance between two successive points of a periodic wave in the direction of propagation, in which the oscillation has the same phase; the distance the wave travels in one period. for light waves three common units of wavelength are: micrometer, nanometer, and angstrom. wave molding, oundy molding, swelled chamfer, undulating molding, undy
