  • \(k = \frac{2\pi}{\lambda}= \frac{2\pi\upsilon}{\upsilon_p}=\frac{\omega}{\upsilon_p}\), where \(\upsilon\) is the frequency of the wave, \(\lambda\) is the wavelength, \(\omega = 2\pi \upsilon\) is the angular frequency of the wave, and \(\upsilon_p\) is the phase velocity of the wave. Alternatively: \(k = \frac{p}{\hbar}\), where \(p\) is the linear momentum of quasi free electrons in an electron gas and \(\hbar\) is the reduced Planck constant (\(h\) divided by \(2\pi\)); for phonons, its magnitude is \(k = \frac{2\pi}{\lambda}\), where \(\lambda\) is the wavelength of the lattice vibrations.

http://qudt.org/sc...inTextDescription
  • "wavenumber" is the spatial frequency of a wave - the number of waves that exist over a specified distance. More formally, it is the reciprocal of the wavelength. It is also the magnitude of the wave vector.
