The maximum energy involved in this effect is given by the equation
The maximum energy involved in this effect is given by the equation h times f minus phi, and it will only occur if h is greater than the work function divided by the threshold frequency. Although it usually occurs with ultraviolet light, it can sometimes occur with sunlight. Discovered in 1887 by Hertz, FTP, what is this effect in which a surface exposed to electromagnetic radiation emits a stream of photons, most associated with the work of Albert Einstein?
