"Photon absorption" refers to the process through which a photon, which is a tiny bundle or particle of light, is absorbed or taken in by an atom, molecule, or material. When a photon is absorbed, it transfers its energy to the absorbing particle, causing a specific reaction like exciting an electron or heating up the material. This absorption of photons plays a crucial role in various scientific applications, such as solar cells, photosynthesis, and the functioning of our eyes.
