Rayleigh wave

The Rayleigh waves used for this purpose are in the ultrasonic frequency range.

This occurs because a Rayleigh wave of lower frequency has a relatively long wavelength.

Since Rayleigh waves decay slowly, they should be detectable over long distances.

These equations were modified to show Rayleigh wave motion.

Rayleigh waves are a type of surface acoustic wave that travel on solids.

It then converges, from above, to the Rayleigh wave velocity in the high frequency limit.

In the case of Rayleigh waves, the motion is of a rolling nature, similar to an ocean surface wave.

The intensity of Rayleigh wave shaking at a particular location is dependent on several factors:

Rayleigh waves are generated from seismic sources described to be active, passive, or a combination of both.

They usually travel slightly faster than Rayleigh waves, about 90% of the surface wave velocity, and have the largest amplitude.

Rayleigh waves on ideal, homogeneous and flat elastic solids show no dispersion.

It is also possible to observe Rayleigh wave dispersion in thin films or multi-layered structures.

In particular, some biologists theorize that elephants may use vocalizations to generate Rayleigh waves.

Local geologic structure can serve to focus or defocus Rayleigh waves, leading to significant differences in shaking over short distances.

After assuming a free surface boundary where no stresses or strains cross, the Rayleigh wave equation is simplified.

The waves that compose most of the secondary microseismic field are Rayleigh waves.

Low frequency Rayleigh waves generated during earthquakes are used in seismology to characterise the Earth's interior.

Surface waves are classified into two basic types, Rayleigh waves and Love waves.

There are two types of surface waves, namely Rayleigh waves and Love waves.

Documented cases of vibrational communication are almost exclusively restricted to Rayleigh waves or bending waves.

This means the velocity of a Rayleigh wave is dependent on the wavelength (and therefore frequency), a phenomenon referred to as dispersion.

However, if a solid or structure has a density or sound velocity that varies with depth, Rayleigh waves become dispersive.

Rayleigh waves include both longitudinal and transverse motions that decrease exponentially in amplitude as distance from the surface increases.

The existence of Rayleigh waves was predicted in 1885 by Lord Rayleigh, after whom they were named.

Rayleigh waves have a speed slightly less than shear waves by a factor dependent on the elastic constants of the material.
