spektoskopia

Spektroskopia is a scientific method used to study the interaction between matter and electromagnetic radiation. It involves passing radiation, such as light, through a sample and then analyzing the resulting spectrum. This spectrum reveals information about the composition, structure, and properties of the sample. Different types of spectroscopy exist, each utilizing a different part of the electromagnetic spectrum or a different interaction mechanism. For instance, absorption spectroscopy measures how much radiation a sample absorbs at different wavelengths, while emission spectroscopy detects the radiation emitted by a sample. Techniques like infrared spectroscopy are valuable for identifying molecular functional groups, while atomic emission spectroscopy is used to determine the elemental composition of a substance. Spectroscopy finds wide applications in various fields, including chemistry, physics, astronomy, and biology. In chemistry, it's crucial for identifying unknown compounds and monitoring chemical reactions. Astronomers use spectroscopy to analyze the light from stars and galaxies, providing insights into their temperature, composition, and motion. In medicine, it aids in disease diagnosis and drug development. The fundamental principle behind spectroscopy is that atoms and molecules absorb or emit radiation at specific, characteristic wavelengths, creating a unique spectral fingerprint. Analyzing this fingerprint allows scientists to deduce a wealth of information about the material under investigation.
