Experiment 6 - The Photoelectric Effect. where E is the energy of the radiation, f is its frequency, and h is Planck's constant (6.63Ã10-34 Js). The notion of light quantization was first introduced by Planck. Its validity is based on solid experimental evidence, most notably the photoelectric effect.
