WebWavenumbers, Dispersion Relations, and Momenta As described above, when waves enter media, their effective velocity can change and so the effective wavelength changes as well. Since k = \frac {2\pi} {\lambda} k = λ2π, these effects are equivalently captured by the change in wavenumber. WebWavenumber is denoted by lower case letter "k". In order to better understand wavenumber, we have to start with the Helmholtz equation, which can be derived from Maxwell's Equations if you're a better man that the rest of us (and you're welcome to take over this part of the lesson!)

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. A wavetrain (denoted by some variable X) can be regarded as a one-parameter family of such hypersurfaces in spacetime. This variable X is a scalar function of position in spacetime. The derivative of this scalar is a vector that characterizes the wave, the four-wavevector.
