Is Wavenumber Directly Proportional To Frequency?
Is Wavenumber Directly Proportional To Frequency? For electromagnetic radiation in vacuum, wavenumber is directly proportional to frequency and to photon energy. Because of this, wavenumbers are used as a convenient unit of energy in spectroscopy. Are wavenumber and wavelength directly proportional? Spectroscopists use wavenumber as a unit that is proportional to energy and is convenient
