Emission and Absorption Lines Feature Summary
- From Physics Research
- The continuous spectrum with dark absorption lines, which is shown twice above, is sunlight, and the emission lines, in the other spectra, are from the elements indicated--magnesium, hydrogen, and sodium. For the difference between absorption lines and emission lines, see the diagram in Continuous, Emission and Absorption Spectra and also in Solar Spectrum.
Can you match any of these emission lines to absorption lines in the solar spectrum? For a simulation of the spectra of many common elements, see Spectra of Gas Discharges.
