Rayleigh distribution formula ocean wave
Rayleigh waves are a type of surface wave that travel near the surface of solids. Rayleigh waves include both longitudinal and transverse motions that decrease exponentially in amplitude as distance from the surface increases. There is a phase difference between these component motions. The existence of Rayleigh waves was predicted in 1885 by Lord Rayleigh, after … Webthat random wave heights, H, followed the Rayleigh Probability Distribution (named for Lord Rayleigh who showed its applicability to the amplitude of sound waves in 1877). Rayleigh …
