• Each of the 92 elements emits a characteristic spectrum.
• Visible light interacts with atoms and molecules to produce characteristic spectrums, patterns that reveal chemical composition.
• The most common light sources are thermal : a body at a given temperature emits a characteristic spectrum of black-body radiation.
