Photoelectric Effect
As shown in the graph below, electron energy increases with frequency in a simple linear manner above the threshold. All three curves have the same slope (equal to Planck's constant) which shows that the energy-frequency relation is constant for all materials. Below the threshold frequency photoemission does not occur.

The photoelectric effect would be a key to demonstrating Einstein's brilliance. Consider the following five properties of the photoelectric effect. All of these properties are consistent with the idea that individual photons of EM radiation are absorbed by individual electrons in a material, with the electron gaining the photon's energy.
The Photoelectric Effect
The photoelectric effect is a phenomenon in which electrons are ejected from the surface of a metal when light is incident on it. These ejected electrons are called photoelectrons. It is important to note that the emission of photoelectrons and the kinetic energy of the ejected photoelectrons is dependent on the frequency of the light that is ...

Often the photoelectric equation is illustrated on a graph of KE vs frequency. On this graph, the slope ALWAYS equals Planck's constant, 6.63 x 10-34 J sec. It NEVER changes. All lines on this type of graph will be parallel, only differing in their y-axis intercept (-f) and their x-axis intercept (the threshold frequency).
