Find the correct statement$(s)$ about the photoelectric effect.

  • A
    There is no significant time delay between the absorption of suitable radiation and the emission of electrons.
  • B
    Einstein's analysis gives a threshold frequency below which no electron can be emitted.
  • C
    The maximum kinetic energy of the emitted photoelectrons is directly proportional to the frequency of incident radiation.
  • D
    The maximum kinetic energy of electrons does not depend on the intensity of radiation.
