WebOct 3, 2011 · Rayleigh waves are formed under the conditions where multiple reflections of P and S waves sum up to make a bigger, slower (group velocity) wave which expands cylindrically. Also, Rayleigh waves are "surface waves", which means that they only propagate at and a few hundred km below the surface (they get weaker with depth). May … Rayleigh waves are a type of surface acoustic wave that travel along the surface of solids. They can be produced in materials in many ways, such as by a localized impact or by piezo-electric transduction, and are frequently used in non-destructive testing for detecting defects. Rayleigh waves are part of the … See more 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 … See more Rayleigh waves are widely used for materials characterization, to discover the mechanical and structural properties of the object being … See more Generation from earthquakes Because Rayleigh waves are surface waves, the amplitude of such waves generated by an earthquake generally decreases exponentially with the depth of the hypocenter (focus).
