Light behaves as both a wave and a particle, depending on how it is measured. This dual nature, called wave-particle duality, was among the most disorienting findings of early twentieth-century physics, and it eventually applied to electrons and other matter as well. Today, physicists treat the duality not as a paradox to be resolved but as a foundational feature of quantum reality.
Which choice best states the main idea of the text?
- Acheck_circle
Wave-particle duality is treated as a fundamental feature of quantum physics, not a problem to be solved.
- B
Light is more wave than particle.
- C
Electrons are not subject to duality.
- D
Physics has progressed beyond quantum theory.
Explanation
The passage's central point is that physicists now accept duality as foundational — A. B, C, and D contradict or distort the text.
