thumb|A Prism (optics)|prism separates white light by dispersing it into its component colors, which can then be studied using spectroscopy.

AI overview

Spectroscopy is a technique that separates light into its component colors (often using a prism) so that scientists can study them in detail. It matters because analyzing these individual colors reveals information about the composition and properties of the materials or objects that produced the light.

Spectroscopy is the field of study that measures and interprets electromagnetic spectra as it interacts with matter. In narrower contexts, spectroscopy is the precise study of color as generalized from radiated visible light to all bands of the electromagnetic spectrum.
