Absorptiospektrots

Absorptiospektrots, often translated as absorption spectrum, refers to the range of wavelengths of electromagnetic radiation that have been absorbed by a substance. When light or other radiation passes through a material, certain wavelengths are absorbed, while others are transmitted or reflected. The resulting pattern of absorbed wavelengths is characteristic of the substance's chemical composition and electronic structure.

An absorption spectrum is typically displayed as a graph with intensity or absorbance plotted on one axis and wavelength on the other. Peaks in the spectrum indicate wavelengths that are strongly absorbed by the substance. Conversely, regions with no absorption show up as dips or flat lines, representing wavelengths that are transmitted. Different types of molecules and atoms interact with electromagnetic radiation in unique ways, leading to distinct absorption spectra.

The study of absorption spectra is a fundamental technique in various scientific fields. Spectroscopy, the science of analyzing spectra, utilizes absorption spectra for identifying and quantifying substances, determining molecular structures, and studying chemical reactions. For instance, astronomers use absorption spectra of stars to determine their chemical makeup and temperature. In chemistry, it's used to identify unknown compounds and monitor reaction progress. This principle is also applied in fields like environmental monitoring and medical diagnostics.
