Notes
Unit of wavelength employed in atomic and molecular physics. Named after the Swedish scientist A.J. Ångström (1814-1874), it is based on the wavelength of the emission spectra's red line of an atom of cadmium. The agreed numerical value is equal to l=6438.4696 Å in dry air which contains at maximum a volume fraction of carbon dioxide of 30x10-6, and measured under standard atmospheric pressure and at 10°C.
