Einstein was trying to explain the photoelectric effect phenomenon, when laboratory studies showed that increasing the intensity of the light falling on the surface increased the number of electrons ejected from the surface, but not their energy.

Einstein said that all radiation (whether from a blackbody or otherwise) must come in small bundles, called photons. The energy, E, of a photon with a frequency ν is given by:

\[E=h\nu\]
