The energy of an individual photon is given by #E=h * nu#; where #h# is Planck's constant and #nu# is the frequency of the photon.

If the photon's energy exceeds the binding energy of a surface electron (typically in a metal), then the electron can be ejected from the surface. Any energy in excess of the binding energy appears as kinetic energy of the ejected electron. This is the photoelectric effect.
