  • The Photoelectric Effect

    • This is called the photoelectric effect, and the electrons emitted in this manner are called photoelectrons.
    • The energy of the individual photoelectrons increased with the frequency (or color) of the light, but was independent of the intensity (or brightness) of the radiation.
    • As the frequency of the incoming light increases, each photon carries more energy, hence increasing the energy of each outgoing photoelectron.
