wave-particle duality


General Science

  • noun
    (written as wave–particle duality)
    the quantum concept that energy can behave as either a particle or a wave


  • The dual nature of electromagnetic radiation, in which it has particle-like properties, as seen in the photoelectric effect, and wavelike properties, as evidenced by phenomena such as diffraction and interference. Certain particles such as electrons also exhibit this duality, as they have wavelike properties, as seen, for instance, in electron diffraction. Also called particle-wave duality.
