Davisson and Germer proved experimentally the wave nature of particles under the phenomenon of:
Correct answer: D. Diffraction
- A. Reflection
- B. Refraction
- C. Interference
- D. Diffraction
Explanation
In the Davisson-Germer experiment, electrons were scattered off of a nickel crystal. The resulting diffraction pattern was consistent with the wave nature of electrons. This experiment provided experimental evidence for the wave-particle duality of matter, which was first proposed by Louis de Broglie in 1924.

About Quantum Theory and Radiation
Quantum theory treats electromagnetic radiation as packets of energy called photons, with energy proportional to frequency through E equals hf. The topic covers Planck's hypothesis, photon momentum, the photoelectric effect, threshold frequency, work function and wave particle duality, distinguishing quantised energy exchange from classical continuous radiation.
