Question & Answer
Choose the Best Answer
Einstein's theory of relativity
Wave-particle duality
Photon energy quantization
Classical wave theory
Understanding the Answer
Let's break down why this is correct
The photoelectric effect shows that light gives electrons only when it has enough energy. Other options are incorrect because Einstein used relativity to explain mass–energy equivalence, but the photoelectric effect is about energy carried by light; Wave‑particle duality says light can act as a wave and a particle.
