WebWhen the energy from photons is absorbed by matter, the matter can emit electrons. This process is called the photoelectric effect. The photoelectric effect is a property of light that is not explained by the theory that light is a wave. This is one of the main reasons that scientists chose to treat light as both a wave and a stream of particles. WebThe photoelectric effect is the phenomena in which electrons are emitted from the surface of a metal upon the absorption of electromagnetic radiation. Electrons removed from a metal in this manner are known as photoelectrons. The photoelectric effect provides important evidence that light is quantised, or carried in discrete packets.
