rayleigh wave in a sentence
Examples
- Displacement in Rayleigh waves occurs in a retrograde elliptical motion normal to the surface and parallel to the direction of wave propagation.
- Krylov carried out research into Rayleigh waves, including their propagation at hypersonic frequencies, their propagation and scattering on curved and statistically rough surfaces.
- Rayleigh waves are much slower than body waves, roughly 90 % of the velocity of body waves for a typical homogeneous elastic medium.
- Low frequency ( < 20 Hz ) Rayleigh waves are inaudible, yet they can be detected by many mammals, birds, insects and spiders.
- In the Oklahoma City case, both seismic vibrations are a shallow-earth wave called a Rayleigh wave, after the 19th century English scientist Lord Rayleigh.
- In isotropic, linear elastic materials described by Lame coefficients \ lambda and \ mu, Rayleigh waves have a speed given by solutions to the equation
- One example is Rayleigh waves on the Earth's surface : those waves with a higher frequency travel more slowly than those with a lower frequency.
- This means that the velocity of a Rayleigh wave in practice becomes dependent on the wavelength ( and therefore frequency ), a phenomenon referred to as dispersion.
- 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 ).
- Rayleigh waves, also known as " ground roll ", are waves that travel as ripples with motion similar to those of waves on the surface of water.
