In physics, a wave vector (or wavevector) is a vector used in describing a wave, with a typical unit being cycle per metre. It has a magnitude and direction. Its magnitude is the wavenumber of the wave (inversely proportional to the wavelength), and its direction is perpendicular to the wavefront. In isotropic media, … Zobacz więcej For this article, the terms wave vector and angular wave vector are used with distinct meanings to avoid confusion. Here, the wave vector is denoted by k and the wavenumber by k = k , and the angular wave vector is … Zobacz więcej In solid-state physics, the "wavevector" (also called k-vector) of an electron or hole in a crystal is the wavevector of its quantum-mechanical wavefunction. These electron waves are not … Zobacz więcej • Plane wave expansion • Plane of incidence Zobacz więcej The direction in which the wave vector points must be distinguished from the "direction of wave propagation". The "direction of wave propagation" is the direction of a wave's energy flow, and the direction that a small wave packet will move, i.e. the … Zobacz więcej A moving wave surface in special relativity may be regarded as a hypersurface (a 3D subspace) in spacetime, formed by all the events passed by the wave surface.
