Wave like characteristic of electron is demonstrated by:
Correct answer: B. Diffraction by crystalline solids
- A. Line spectrum of atoms
- B. Diffraction by crystalline solids
- C. Production of X-rays
- D. Photo electric effect
Explanation
The wave-like nature of electrons is demonstrated by electron diffraction, where electrons create interference patterns similar to light waves when passing through a crystal or narrow slit.

About Atomic Spectra
Atoms emit or absorb light at specific wavelengths because electrons occupy quantized energy levels and change levels by absorbing or releasing photons. The topic covers emission and absorption spectra, spectral series, hydrogen’s line spectrum, energy-level transitions, and the relation between wavelength, frequency and photon energy.
