Meaning and Definition
A type of seismic surface wave that travels along the free surface of an elastic solid, with a rolling, elliptical particle motion.
A wave phenomenon in seismology and acoustics characterized by its surface-confined propagation and specific particle displacement, which is retrograde elliptical at the surface. It is also studied in non-destructive testing and geophysics for subsurface imaging.

Common Mistakes When Using “rayleigh wave”
- Misspelling as 'Rayliegh', 'Raleigh', or 'Reilly' wave.
- Confusing it with Love waves (another surface wave with horizontal motion).
- Using it without an article in singular form (e.g., 'Rayleigh wave was detected' instead of 'A Rayleigh wave was detected').
FAQ
Frequently Asked Questions
They were predicted mathematically by Lord Rayleigh (John William Strutt) in 1885.
Rayleigh waves are slower than both P-waves and S-waves, which is why they arrive later on a seismogram.
No, Rayleigh waves require a free surface of an elastic solid and cannot propagate in fluids.
They are used in non-destructive testing and surface acoustic wave (SAW) devices, such as filters in mobile phones.
A type of seismic surface wave that travels along the free surface of an elastic solid, with a rolling, elliptical particle motion.
Rayleigh wave is usually technical/scientific in register.
