Short Answer
Matter has wave-like properties is the best answer.
Quantum questions reward precision with language. Identify whether the prompt is about wave behaviour, measurement, states, operators, or quantised energy levels before choosing a formula or interpretation.
de Broglie proposed λ = h/p — all matter has an associated wavelength.
Why This Answer Is Correct
This is a Easy-level question in Quantum Physics. The prompt is really testing whether you can connect the concept to its defining physical relationship instead of picking a nearby-but-wrong term.
When a quantum question feels ambiguous, translating it into state, observable, probability, and evolution language usually clarifies the answer.
Choices At A Glance
- A. Light travels in waves
- B. Matter has wave-like properties
- C. Electrons are massless
- D. Photons have charge
When similar options appear on an exam, eliminate the ones that break the core law, use the wrong units, or confuse a definition with a consequence.
