Absorption

Spectroscopy Absorption spectroscopy is a technique used to measure the amount of light absorbed by a sample as it passes through a certain wavelength. It is used to identify and quantify different materials, as every material has a unique set of absorption bands, or regions of the spectrum in which it absorbs light. This technique can be used for a wide range of applications such as environmental studies, food safety testing, medical diagnosis, and drug research, among others. It has become a vital tool for examining the structure and composition of materials.
