WebbHertz’s photoelectric effect. Stories from Physics for 11-14 14-16 16-19. Heinrich Hertz made perhaps the earliest recorded observation of the photoelectric effect in 1887, during his experiments on radio waves. Hertz had set up a receiver for radio waves consisting of a spark gap in a curved piece of brass capped with small metal spheres. Webb20 feb. 2024 · For now, we will use the photon concept to explain the photoelectric effect, much as Einstein did. Figure 29.2. 2: An EM wave of frequency f is composed of photons, or individual quanta of EM radiation. The energy of each photon is E = h f, where h is Planck’s constant and f is the frequency of the EM radiation.
