Although Albert Einstein is most famous for E = mc2 and for his work describing relativity in mechanics, his Nobel Prize was for understanding a very simple experiment. It was long understood that if you directed light of a certain wavelength at a piece of metal, it would emit electrons. In classical theory, the energy of the light was thought to be based on its intensity and not its frequency. However, the results of the photoelectric effect contradicted classical theory. Inconsistencies led Einstein to suggest that we need to think of light as being composed of particles (photons) and not just as waves. In this experiment, you will reproduce a photoelectric experiment and show that the energy (E) of a photon of light is related to its frequency and not its intensity.
