<P> Spectroscopy / spɛkˈtrɒskəpi / is the study of the interaction between matter and electromagnetic radiation . Historically , spectroscopy originated through the study of visible light dispersed according to its wavelength , by a prism . Later the concept was expanded greatly to include any interaction with radiative energy as a function of its wavelength or frequency . Spectroscopic data are often represented by an emission spectrum , a plot of the response of interest as a function of wavelength or frequency . </P>
