Spectrum Analysis, the act of ascertaining the character and composition of luminous bodies by causing a ray of light from the body to pass through a prism, each substance in the spectrum having its own characteristic system of lines—as in a star, a planet or any heavenly body in a state of incandescence or in metals submitted by the chemist to great heat. See Spectroscopy.
