What is the phenomenon of the photoelectric effect?

  • A
    Photons are emitted from a metal when it is struck by a beam of electrons.
  • B
    Photons are emitted from the nucleus of an atom under the influence of an electric field.
  • C
    Electrons are emitted from a metal with a constant velocity that depends on the frequency and intensity of the incident light.
  • D
    Electrons are emitted from a metal with velocities not exceeding a certain value, which depends only on the frequency of the incident light.
