Spectral Analysis Library

Spectral (or spectrum) analysis is a scientific method of determining the chemical properties of matter from the bands in their visible spectrum. Watch the NASA video for more information.

Spectroscopes break down the light emitted or absorbed by chemical elements into specific lines of color. Every chemical element has a "fingerprint" of its own that can be used to identify it. These fingerprints are generally produced when electrons change orbital levels as they gain or lose energy. Different energies produce different coloured lines.
