Photoelectric Effect
Electrons are emitted from the surface of a metal when electromagnetic radiation above a certain frequency was directed at the metal.
Einstein's Explanation
Light is composed of wavepackets or photons, each of energy equal to it. When light is incident on a metal surface, an electron at the surface absorbs a single photon from the incident light and therefore gains energy equal to hf. An electron can leave the metal surface if the energy gained from a single photon exceeds the work function of the metal.
Stopping Potential
The minimum potential need to stop photoelectric emission.
