Absorption is the process by which the energy of a photon is taken up by another entity, for example, by an atom which makes a transition between two electronic energy levels. The photon is destroyed in the process. Molecules can lose absorbed energy by heat and radiation. Absorption is often measured by spectroscopy.

It is valid and fundamental in Boolean algebra, and lattice theory. The absorption law states that a $ a % b a % a $ b a''. The interest arises because of the casesAbsorption spectroscopyAbsorption Spectroscopy is an analytical tool used by chemists. It is based on the absorption of quanta of light by a substance, due to the promotion of electrons from one orbital to another in that substance. The absorption spectrum is characteristic for
Absorption spectrumAn absorption spectrum is a diagram depicting the wavelengths of electromagnetic radiation absorbed by a material, usually a gas. It can be regarded as the opposite to an emission spectrum, which is a depiction of the specific wavelengths emitted by a mat
