Spektroskoopiaga, often referred to as spectroscopy, is a scientific method used to study the interaction between matter and electromagnetic radiation. It involves analyzing the spectrum of radiation emitted, absorbed, or scattered by a substance. This spectrum, which is essentially a plot of intensity versus wavelength or frequency, provides a unique fingerprint for that substance.

Different types of spectroscopy exist, each utilizing a specific range of the electromagnetic spectrum, such as visible light, infrared, ultraviolet, X-rays, or radio waves. For instance, atomic absorption spectroscopy is used to measure the concentration of metallic elements in a sample by observing how much light at a specific wavelength is absorbed by free atoms. Infrared spectroscopy, on the other hand, is valuable for identifying functional groups in organic molecules by detecting the absorption of infrared radiation at characteristic frequencies.

The applications of spectroscopy are vast and span numerous scientific disciplines. In astronomy, it's used to determine the composition, temperature, and velocity of stars and galaxies. In chemistry, it's indispensable for identifying unknown compounds, determining molecular structures, and quantifying the amount of substances present. Furthermore, spectroscopy finds applications in medicine for diagnostic purposes, in environmental monitoring to detect pollutants, and in materials science to characterize the properties of different materials. The fundamental principle remains the same: analyzing how matter interacts with light or other forms of electromagnetic radiation to gain insight into its composition and structure.
