Of the following which is the best evidence for the wave nature of matter?
Correct answer: D. The diffraction of electrons by crystals
- A. The photoelectric effect
- B. The Compton effect
- C. The relationship between momentum and energy for an electron
- D. The diffraction of electrons by crystals
Explanation
By Davison-Germer the diffraction pattern (diffraction of electrons by crystals) have been observed with electron, protons, neutron, hydrogen atoms and helium atoms thereby giving substantial evidence for the wave nature of particles.

About Photons and the Particle Model of Light
The particle model treats light as photons with energy E equals hf and momentum related to wavelength. Questions involve the photoelectric effect, work function, threshold frequency, stopping potential and photon energy, while distinguishing particle behaviour from the wave description of interference and diffraction.
