Spectra Units cm^(-1)?

I am seeing units for atomic/molecular spectra listed as ##cm^{-1}##. Is this based on the wave number ##k## for ##\Psi=Asin(kx-\phi)##?

Thanks,
KQ6UP

It is then inverse of the wavelength of the emitted/absorbed light. It is a leftover of the early days of spectroscopy, where this was something relatively easy to measure.
