WebbIn his explanation of the photoelectric effect, Einstein defined a quantized unit or quantum of EM energy, which we now call a photon, with an energy proportional to the frequency of EM radiation. In equation form, the photon energy is \ [E = hf,\] where \ (E\) is the energy of a photon of frequency \ (f\) and \ (h\) is Planck’s constant. WebbThe photoelectric effect was first observed in 1887 by Heinrich Hertz during experiments with a spark gap generator (the earliest device that could be called a radio). In these …

WebbThe 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. WebbIn 1887, Heinrich Hertz observed the photoelectric effect and the production and reception of electromagnetic waves, also known as the Hertz effect.
