Target entity: Davisson–Germer experiment
Context triple: [Lester Germer, notableWork, Davisson–Germer experiment]
  • A. Davisson–Germer experiment chosen
    The Davisson–Germer experiment was a landmark 1927 physics experiment that demonstrated the wave nature of electrons through diffraction from a nickel crystal, providing key evidence for quantum mechanics and wave–particle duality.
  • B. Franck–Hertz experiment
    The Franck–Hertz experiment is a landmark early-20th-century physics experiment that provided direct evidence for the quantization of atomic energy levels, supporting the Bohr model of the atom.
  • C. Geiger–Marsden experiment
    The Geiger–Marsden experiment, also known as the gold foil experiment, was a landmark early 20th-century physics experiment that revealed the existence of a small, dense atomic nucleus and led to the development of the Rutherford model of the atom.
  • D. Ives–Stilwell experiment
    The Ives–Stilwell experiment is a classic test of special relativity that measured the relativistic Doppler effect to confirm time dilation for fast-moving ions.
  • E. Trouton–Noble experiment
    The Trouton–Noble experiment was an early 20th-century test of the luminiferous aether that searched for a torque on a charged capacitor in motion and, by finding no such effect, provided support for the emerging theory of special relativity.
  • F. None of above.
  • G. Unsure - the case is ambiguous/there is not enough information to decide.
