1. n. [Geophysics]

A periodic vibrational disturbance in which energy is propagated through or on the surface of a medium without translation of the material. Waves can be differentiated by their frequency, amplitude, wavelength and speed of propagation.

Wavelength is defined as:

λ = v / f,

where
λ = wavelength
v = speed of propagation
f = frequency.
