absorption spectra

İngilizce - Türkçe

ABSORPTION SPECTRA
Absorption spectra refers to the pattern of wavelengths of light that are absorbed by a material, such as a gas, liquid or solid. When a beam of light passes through a material, some of the energy is absorbed by the material, and this results in the attenuation of the light. The amount of light absorbed at each wavelength is measured using a spectrophotometer, which measures the intensity of the light before and after it passes through the material. The resulting plot of the intensity of the transmitted light versus the wavelength of the light is known as the absorption spectrum.

Absorption spectra are widely used in many fields, including chemistry, physics, and astronomy. They can provide information about the electronic and molecular structure of a substance, as well as its composition and purity. For example, in chemistry, absorption spectra are often used to identify compounds and to study their properties, while in astronomy, absorption spectra are used to study the composition of stars and planets.
