      By the early part of the twentieth century, the wave theory of light was well entrenched. But in 1905, German physicist Albert Einstein (emigrated to the U.S. in 1933) discovered that he could explain a phenomena known as the photoelectric effect by postulating tht light had both wave

      Albert Einstein adapted Planck’s idea in 1905 to explain a phenomenon known as the photoelectric effect. The photoelectric effect was first discovered by Hertz in his experiments to investigate Maxwell’s theory of electromagnetic radiation.

      The Photoelectric Effect (At virtually the same time (1897) Heinrich Hertz discovered the photoelectric effect while investigating electromagnetic waves and J. J. Thompson discovered the electron. Hertz found that when light was shown upon a metal surface in an evacuated chamber a current flowed in an external circuit. Figure 1

      May 11, 2013 · The photoelectric effect was explained by Einstein when he conjectured that Planck’s bundles of energy (i.e. photons) were “knocking loose” the electrons—but only if the photons had enough energy to do the job (a two year old isn’t able to knock a football player off his feet, but a bull undoubtedly could).

      The photoelectric effect occurs when electrons are emitted from a metallic surface irradiated by a suitable light source. Einstein’s explanation of this effect required the assumption that light is made up of particles, called photons, each carrying a definite energy specified by the formula
