It was discovered by accident by Heinrich Hertz in 1887 while he was generating electromagnetic waves and observing their propagation.
It was discovered by accident by Heinrich Hertz in 1887 while he was generating electromagnetic waves and observing their propagation. According to the classical wave theory of light, the intensity of the light determines the amplitude of the wave, and so a greater light intensity should cause the electrons on the metal to oscillate more violently and to be ejected with a greater kinetic energy. However, the experiment showed that the kinetic energy of the ejected electrons depends only on the frequency of the light. FTP, what is this effect which was explained in 1905 by Albert Einstein?
