The electron is purely a _ when free.
Correct answer: C. Dual nature
- A. Particle nature
- B. Wave nature
- C. Dual nature
- D. It transforms to photon
Explanation
The electron is purely a dual nature when it's free. In quantum mechanics, electrons can behave as both particles and waves, depending on how they are observed or measured. This duality is known as wave-particle duality and is a fundamental aspect of quantum mechanics. When electrons are free, meaning they are not bound within an atom or molecule, their wave-like properties become more apparent.

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.
