Answer:
The angular wavenumber may be expressed in radians per meter (rad. m−1), or as above, since the radian is dimensionless. For electromagnetic radiation in vacuum, wavenumber is proportional to frequency and to photon energy. Because of this, wavenumbers are used as a unit of energy in spectroscopy.
