The method of producing spectra called spectroscopy?

Spectroscopy is a technique used to study the interaction between matter and electromagnetic radiation. It involves the measurement of the intensity of light at different wavelengths, which can provide information about the composition, structure, and properties of a material. Spectroscopy can be used in various fields such as chemistry, physics, astronomy, and biology to analyze samples and identify unknown substances. There are different types of spectroscopy techniques, including absorption spectroscopy, emission spectroscopy, and mass spectrometry, each of which has its own specific applications and uses.
