The electron is purely a _ when free.

Correct answer: C. Dual Nature

  • A. Particle Nature
  • B. Wave Nature
  • C. Dual Nature
  • D. Transforms to Photon

Explanation

Correct Option: CThe electron exhibits both particle and wave-like properties, as described by the concept of dual nature in quantum mechanics. This duality means that the electron can exhibit characteristics of both particles and waves, depending on the experimental conditions and observations. Therefore, option C, "Dual Nature," is the correct choice.

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.
