Web2006). Rayleigh waves are the result of the interference between compressional (P) and shear (S) waves. The greatest effect on the Rayleigh wave dispersion is exerted by the S-wave velocity (Sun et al., 2024). Therefore, the S-wave velocity is normally obtained by inverting the dispersed phase velocities of Rayleigh WebRayleigh scattering (/ ˈ r eɪ l i / RAY-lee), named after the 19th-century British physicist Lord Rayleigh (John William Strutt), is the predominantly elastic scattering of light or other electromagnetic radiation by particles much smaller than the wavelength of the radiation.
