The Davisson and Germen experiment indicate:
Correct answer: B. Electron diffraction
- A. Interference
- B. Electron diffraction
- C. Polarization
- D. Refraction
Explanation
The experiment shows diffraction of electron through metal crystals.In 1927, C.J. Davisson and L.H. Germer performed an experiment known as the Davisson Germer experiment to explain the wave nature of electrons through electron diffraction.

About Dawn of Modern Physics
Classical physics cannot explain blackbody radiation and related observations, leading to Planck’s quantum theory, in which energy is emitted or absorbed in discrete packets. Photons provide the particle model of light, with energy and momentum linked to frequency and wavelength, including the photoelectric effect and its threshold frequency.
