SPECTROSCOPY

Spectroscopy is the science which deals with the methods of production of the spectra from various sources of light, and their study.
The science of spectroscopy began properly with Kirchoff's interpretation of the Fraunhofer lines in 1859, that they indicated gases and metallic vapours surrounding the incandescent body of the sun.
