"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 … " - Rayleigh particle

Web2. Rayleigh scattering • Because the sizes of atmospheric molecules are much smaller than the wavelengths of solar and IR radiation, the scattering by atmospheric gases is the Rayleigh scattering. • In the Rayleigh scattering approximation, a molecule (or a small particle) is considered as an individual dipole. WebRayleigh wave energy is dispersive meaning that different frequencies travel with different velocities. More specifically, each frequency travels with a phase velocity that is mostly a function of the average shear-wave velocity of the subsurface from the ground surface to the base of particle motion associated with that frequency (wavelength).
