How many spectral lines




















The electron energy level diagram for the hydrogen atom. Summary Emission lines for hydrogen correspond to energy changes related to electron transitions. The Bohr model works only for the hydrogen atom. Can you see the Lyman series with the naked eye? Which series can we at least partially see? What happens to the hydrogen gas in a discharge tube? Review What happens when a hydrogen atoms absorbs one or more quanta of energy? How do we detect the change in energy?

What electron transitions are presented by the lines of the Paschen series? Does the Bohr model work for atoms other than hydrogen?

The spectral lines of a specific element or molecule at rest in a laboratory always occur at the same wavelengths. For this reason, we are able to identify which element or molecule is causing the spectral lines. If the emitter or absorber is in motion, however, the position of the spectral lines will be Doppler shifted along the spectrum. There are two types of spectral lines in the visible part of the electromagnetic spectrum: Emission lines — these appear as discrete coloured lines, often on a black background, and correspond to specific wavelengths of light emitted by an object.

Absorption lines — these appear as dark bands, often superimposed on a coloured continuum , and are the result of specific wavelengths being absorbed along the line-of-sight.
