👉 A flash is an electrical phenomenon that occurs when a charged particle, such as a photon, is emitted from a source of light or other electromagnetic radiation. When this particle travels through space and encounters another charged particle, they are able to collide and create a flash of light. In the context of flites, it refers to the process by which an electron (which is part of the atom) gains energy by emitting a photon (a type of electromagnetic wave). When this happens, the electron becomes excited
