Spectroscopy

Spectroscopy relates to the scattering an object's light into its component colors (i.e. energies). By performing the spectroscopy of an object, astronomers can find out the physical properties of that object (like temperature, mass, luminosity and composition). Historically spectroscopy was defined as the use of visible light dispersed according to its wavelength. After that this concept was developed greatly to comprise any kind of measurement of a quantity as a function of either wavelength or frequency. The various devices used in Spectrometry are spectrometers, spectrophotometers, spectrographs or spectral analyzers. Absorption of infrared radiation brings about changes in molecular vibrations within molecules and measurements of the ways in which bonds vibrate gives rise to infrared spectroscopy. Mass spectrometry is other analytical technique, which separates the ions according to their mass/charge ratio
