Atomic absorption spectroscopy is based on the atomic spectra of the elements being studied. It can be used to determine the impurities in a metal sample. If an element is present, light at the appropriate wavelength is absorbed. You are working with a metal stamping company and the rolled steel you use to form panels for automobile doors is failing at an alarming rate. There is some chance that the problem is unacceptably high level of manganese in the steel. Given that atomic spectrum of manganese has three lines near 403 nm, using spectrometer the amount of manganese in the steelshould be determined.
Heat energy is absorbed by the electrons present in the atoms, which allow then to move into the higher energy levels. The light which is emitted matches the atom’s energy levels, and so has specific colors. Since, each atom has different levels of energy, each atom will produce different emission and absorption spectra.
