Spectroscopy
Spectroscopy is the study of how matter interacts with electromagnetic radiation, used to identify the chemical composition and physical properties of distant objects.
TECHNICAL DEFINITION
Spectroscopy is the scientific technique that analyzes the interaction between matter and electromagnetic radiation as a function of wavelength or frequency, enabling the determination of chemical composition, temperature, velocity, and magnetic fields of astronomical objects by examining their emitted, absorbed, or reflected light spectra.
