The Atomic Spectroscopy Group provides standardized measurements used across wide swaths of science and industry. The Trump ...

Studying the line spectra produced by hot gases and absorbed by cooler gases allows us to identify the elements in stars. When a gas is very hot, it doesn’t emit all wavelengths of light.

1\). Line spectra are produced when electrons move from one energy level within an atom to another energy level. \(2\). The energy levels in the atom have definite values. \(3\). Line spectra are ...

provides the definitive measurements of atomic spectra. Spectra are specific sets of colors emitted by different atomic elements. Those sets of colors act as atomic fingerprints that are used to ...
