The Photoelectric Effect
The experiment that revealed light can behave like a stream of particles.
Photoelectric Effect
When light of sufficiently high frequency strikes a metal surface, electrons are emitted. This could not be explained by treating light purely as a wave.
Einstein's Photoelectric Equation
E = hν = φ + KEmax
The energy of an incoming photon equals the work function (φ, the minimum energy needed to free an electron) plus the maximum kinetic energy of the emitted electron.
