Title: Line spectra
Caption: Line spectra of selected elements. Some of the components of the light emitted by excited atoms appear as colored lines. A continuous spectrum is shown at the top for comparison. The numbers are wavelengths of light given in Angstrom units (1 Å = 10-10 m). Each element has its own characteristic line spectrum that is different from all others and can be used to identify the element.
