Einstein's equation of photoelectric effect
Did you know?
WebThe photoelectric effect is caused by the absorption of electromagnetic radiation and consists of electron ejection from a solid (or liquid) surface, usually of a metal, though nonmetals have also been studied. In the case of a gas, the term photoionization is more common, though there is basically little difference between these processes. In spite of …
http://physics.bu.edu/~duffy/EssentialPhysics/chapter27/section27dash2.pdf WebEinstein’s theory of photoelectric effect is based on the revolutionary idea of Planck that light was a particle. The energy transferred to every light particle, quanta or photon depends on the frequency (v) of light, shown by the photoelectric effect equation. E= hv.
