@Spectroscopy: sodium and potassium doublets

(Adolf Cortel, December 2012) The video shows how the sodium doublet observed in the emission of a low pressure sodium lamp coincides with the doublet due to absorption in Fraunhofer's lines. The potassium doublet is easily observed (in the IR) with potassium iodide in a flame. The measurement of the wavelength difference in both doublets can be done with a Fabry Perot interferometer from the positions where the interference fringes overlap when one mirror is displaced.
