B) interference
C) photoelectric effect
D) refraction

Question

Quizplus · Accepted Answer

The photoelectric effect is an experiment that demonstrates the particle nature of light. In this experiment, when a beam of light is shone on a metal surface, electrons are emitted from the metal only if the light energy is above a certain threshold frequency. This can be explained by the idea that light behaves as particles, known as photons, with each photon having a specific energy related to its frequency.
