Target entity: Davisson–Germer experiment Context triple: [Lester Germer, hasNotableExperiment, 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.
