D) Bohr

Question

Quizplus · Accepted Answer

Einstein was the first to successfully explain the photoelectric effect. He proposed that light is made up of discrete packets of energy, called photons, and that each photon has a specific energy proportional to the frequency of the light. When a photon strikes a metal surface, it can transfer its energy to an electron in the metal, causing the electron to be emitted. The maximum kinetic energy of the emitted electrons is proportional to the frequency of the light, which is consistent with the experimental observations of the photoelectric effect.
