Wave-like characteristic of electron is demonstrated by______________?
Correct answer: C. Diffraction by crystalline solids
- A. Line spectrum of atoms
- B. Production of x-rays.
- C. Diffraction by crystalline solids
- D. Photoelectric effect
Explanation
Electron wave behaviour is demonstrated by electron diffraction from crystalline solids, where the regularly spaced atomic planes act like a diffraction structure. The likely wrong choice is photoelectric effect, which demonstrates the particle nature of light rather than the wave nature of electrons.

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.
