*a ‘grebe’ making waves*
.
-as of [21 SEPTEMBER 2024]-
.
.
-in ‘physics’, a “surface wave” is a ‘mechanical wave’ that ‘propagates’ along the ‘inter-face’ between differing ‘media’, usually as a ‘gravity wave’ between 2 fluids with different densities-
.
(a surface wave can also be an elastic (or a seismic) wave, such as with a rayleigh or love wave)
(it can also be an electromagnetic wave guided by a refractive index gradient, or along an interface between two media having different dielectric constants)
.
(in radio transmission, a “ground wave” is a surface wave that propagates close to the surface of the earth)
