According to the wave-particle duality, identify respectively how all micro-particles (electrons, protons, atoms, etc) behave when propagating and when exchanging energies
Correct answer: A. Waves, particles
- A. Waves, particles
- B. Particles, waves
- C. Particles, particles
- D. Waves, waves:
Explanation
Explanation: Wave-particle duality states that micro-particles exhibit both wave-like and particle-like properties. When propagating (moving through space), they behave as waves (e.g., diffraction, interference). When exchanging energies (e.g., in interactions, emissions, absorptions), they behave as particles (e.g., photoelectric effect).

About Dawn of Modern Physics
Classical physics cannot explain blackbody radiation and related observations, leading to Planck’s quantum theory, in which energy is emitted or absorbed in discrete packets. Photons provide the particle model of light, with energy and momentum linked to frequency and wavelength, including the photoelectric effect and its threshold frequency.
