De-Broglie waves are associated with:
Correct answer: A. Moving charged particles only
- A. Moving charged particles only
- B. Moving neutral particles only
- C. All moving particles
- D. All particles whether in motion or at rest
Explanation
De-Broglie waves are associated with moving charged particles, such as electrons and other charged particles, according to Louis de Broglie's wave-particle duality hypothesis. These waves are a fundamental concept in quantum mechanics and provide a wave-like description for the behavior of particles with non-zero mass when they are in motion.

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.
