During absorption, an electron takes energy from an incoming photon, and the internal energy of the electron increases. During spontaneous emission, the internal energy of an electron decreases, and a photon is emitted.

Reactions that absorb energy: Photosynthesis absorbs energy from sunlight, allowing plants to make glucose and oxygen from carbon dioxide and water.
Energy absorption refers to the process of dissipating the input energy from external loading by plastic deformation or fracture. This chapter illustrates how to efficiently utilize plastic deformation to achieve energy absorption.
Absorption is said to occur when radiation passes through matter and interacts with the ions, atoms, or molecules constituting the sample in such a way that they gain energy and move from a quantized low-energy state to a higher energy state.
Different materials absorb photons of different wavelengths because absorption of a photon is an absorption of energy. Something must be done with that energy. In the case of ultraviolet and visible light, the energy is of the right general magnitude to excite an electron to a higher energy level.

Jul 15, 2021 · Adsorption vs Absorption – Differences and Examples. Adsorption occurs when particles stick to the surface of another phase, while absorption occurs when particles enter the bulk of the other phase. Adsorption and absorption are two sorption processes through which one substance attaches to another. The main difference between them is that ...
