PHOTOELECTRIC EFFECT Introduction
... the electrons in the metal absorb a sufficient amount of energy from the light to escape from the metal. This energy is called the binding energy or work function Φ. The work function is different for each type of metal. Energy absorbed in excess of this binding energy is carried off by the electron ...

... When UV light shines on a clean metal surface, electrons are emitted. What is unusual is the way they are emitted. They are emitted immediately, even in weak light. According to the wave interpretation of light, a time delay is needed for enough energy at a given spot to build up to release an elect ...
