The wave nature of an electron is illustrated by its
Correct answer: D. Diffraction
- A. Photoelectric effect
- B. Compton effect
- C. Penetrating effect
- D. Diffraction
Explanation
Diffraction is a phenomenon observed when electrons are passed through a narrow slit, demonstrating their wave-like behavior as they interfere with each other. This supports the wave-particle duality of electrons.

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.
