AAbsolute simultaneity
BPerpetual motion
CUniversal gravitation
DWave-particle duality
Answer & Solution
Correct answer: D. Wave-particle duality
1. Treating light as packets changed how light itself was understood.
2. Photons are individual energy packets of electromagnetic waves.
3. This new model for light provided a foundation.
4. It founded one of the most important ideas in quantum theory, wave-particle duality.
