Emission spectrum for sodium
WebLine emission and absorption spectra Studying the line spectra produced by hot gases and absorbed by cooler gases allows us to identify the elements in stars. When matter is very hot it emits light. WebSep 21, 2024 · Figure \(\PageIndex{8}\): The emission spectra of sodium and mercury. Sodium and mercury spectra. Many street lights use bulbs that contain sodium or mercury vapor. Due to the very different emission spectra of these elements, they emit light of different colors. The lines in the sodium lamp are broadened by collisions.

WebIf you place the sodium lamp in front of the smaller optical rail, you can show the sodium emission line. The grating on the small rail is aimed so that this emission line appears below the dark line in the continuous spectrum. The orange emission line is actually a doublet, the sodium D 2 P 3/2 and the 2 P 1/2 excited states, respectively, to ... Weban emission spectrum or emission-line spectrum. An absorption spectrum is produced when a continuum passes through "cooler" gas. Photons of the appropriate energies are absorbed by the atoms in the gas. Although the photons may be re-emitted, they are …
