This equation just expresses conservation of energy with being the photon energy and the binding energy of electrons in the solid. Data from the Photoelectric effect strongly supported the hypothesis that light is composed of particles (photons). einstein's photoelectric equation According to Plank's quantum theory, light is emitted from a source in the forms of bundles of energy called photons. Energy of each photon is .

Einstein’s Explanation of Photoelectric Effect. Einstein resolved this problem using Planck’s revolutionary idea that light was a particle. The energy carried by each particle of light (called quanta or photon) is dependent on the light’s frequency (ν) as shown: E = hν.
