Which of the following particles exhibits the phenomenon of wave-particle duality as proposed by Louis de Broglie?

A. Only electrons
B. Only photons
C. Only microscopic particles
D. All material particles in motion✓ Correct Answer

💡 Solution & Explanation

Louis de Broglie postulated that all moving matter, regardless of mass or scale, exhibits wave-particle duality with an associated wavelength inversely proportional to momentum. Confining this property only to microscopic particles ignores the universal nature of the de Broglie wavelength formula. This concept forms a foundational pillar of modern quantum mechanics.
