In physics a wave is a disturbance or oscillation that travels through spacetime, accompanied by a transfer of energy. Wave motion transfers energy from one point to another, often with no permanent displacement of the particles of the medium—that is, with little or no associated mass transport. They consist, instead, of oscillations or vibrations around almost fixed locations. Waves are described by a wave equation which sets out how the disturbance proceeds over time. The mathematical form of this equation varies depending on the type of wave.

Some articles on wave:
... A Kelvin wave is a wave in the ocean or atmosphere that balances the Earth's Coriolis force against a topographic boundary such as a coastline, or a waveguide such as the equator ... A feature of a Kelvin wave is that it is non-dispersive, i.e ... the phase speed of the wave crests is equal to the group speed of the wave energy for all frequencies ...
... Consider a plane wave propagating in an anisotropic medium, with a relative permittivity tensor ε, where the refractive index n, is defined by (assuming a relative magnetic permeability ) ... If the wave has an electric vector of the form (2) where r is the position vector and t is time, then the wave vector k and the angular frequency ω must satisfy Maxwell's equations in the medium, leading to ... Therefore, for each direction of the wave normal, two wavevectors k are allowed ...
... bands mixed elements of dark wave and ethereal wave with later developments in electronic music ...
... Dark Wave or darkwave is a music genre that began in the late 1970s, coinciding with the popularity of New Wave and post-punk ... Building on those basic principles, dark wave added dark, introspective lyrics and an undertone of sorrow for some bands ... In the 1980s, a subculture developed alongside dark wave music, whose members were called "wavers" or "dark wavers" ...

Famous quotes containing the word wave:
“Wind goes from farm to farm in wave on wave,
But carries no cry of what is hoped to be.
There may be little or much beyond the grave,
But the strong are saying nothing until they see.”
—Robert Frost (18741963)
“We are caught up Mr. Perry on a great wave whether we will or no, a great wave of expansion and progress. All these mechanical inventionstelephones, electricity, steel bridges, horseless vehiclesthey are all leading somewhere. Its up to us to be on the inside in the forefront of progress.”
—John Dos Passos (18961970)
“And his wish is intimacy,
And a stricter privacy;
The impossible shall yet be done,
And, being two, shall still be one.
As the wave breaks to foam on shelves,
Then runs into a wave again,
So lovers melt their sundered selves,
Yet melted would be twain.”
—Ralph Waldo Emerson (18031882)
