TopNewestSpectroscopy was originally the study of the interaction between radiation and matter as a function of wavelength. In fact, historically, spectroscopy referred to the use of visible light dispersed according to its wavelength, e.g. by a prism.

Spectroscopy is the study of the interaction between matter and radiated energy.

Definition: Spectroscopy is the use of light, sound or particle emission to study matter. The emissions are, in many cases, able to provide information about the properties of the matter under investigation. The device often used for such analysis is a spectrometer, which records the spectrum of light emitted (or absorbed) by a given material, especially in analytical chemistry and physical chemistry fields, where the light can be used to determine the chemical composition of a substance because of signature spectral lines emitted by known elements.

Spectroscopy pertains to the dispersion of an object's light into its component colors (i.e. energies). By performing this dissection and analysis of an object's light, astronomers can infer the physical properties of that object (such as temperature, mass, luminosity and composition).Spectroscopy was originally the study of the interaction between radiation and matter as a function of wavelength (''λ''). In fact, historically, spectroscopy referred to the use of visible light dispersed according to its wavelength, e.g. by a prism.
