Atomic spectral lines are the various frequencies of radiation emitted by atoms. They are continual in nature, so they can be used to identify different elements when studied via spectroscopy. Atomic spectral lines are the \\"fingerprints\\" of elements, as each element emits a different set of spectral lines.

Atomic spectral lines are measured in terms of frequency, wavelength, and energy. It is important to note that each element has a unique set of spectral lines, which helps scientists determine which element they are looking at without having to actually identify it. For example, if a scientist observes a set of spectral lines in the visible range of light, they can determine it is coming from hydrogen because no other element emits the same set of spectral lines.

Atomic spectral lines can be used for a variety of purposes. For example, they are often used to identify elements in stars, in creating a chart of their composition. Additionally, they are used to detect potential pollutants in the atmosphere, as certain pollutants emit characteristic spectral lines.

In conclusion, atomic spectral lines are a useful tool for astronomers and scientists. By analyzing the set of spectral lines emitted by an atom, scientists can identify which element is present and use it for numerous purposes.
