In some situations when a beam of light is directed at a metal surface, an electron is emitted. This happens because the photons in the light -
combine with metal atoms to create electrons, which scape.
are transformed into electrons with enough energy to escape.
transfer their energy to an electron, helping the electron escape.
are destroyed on impact, generating electrons which scape.
