Hyperphysics photoelectric effect

WebThe Photoelectric effect In the photoelectric effect, electrons are emitted from a material when light is incident on its surface. Ordinarily an electron is bound to the material and cannot escape from it unless energy is supplied. The light must supply each emitted electron with sufficient energy to escape from the surface.
