What is Spectroscopy?

Spectroscopy in the study of chemistry or physics is the learning of emission or absorption radiations from matter (atom, ion, and molecule) when dispersed through a suitable prism. Spectroscopy is the most important tool for determining the structure of an atom, ion, or molecule. The atom of an element always produces the line spectra which are also called atomic spectra.
