Which phenomenon demonstrates the particle nature of light as explained by the photoelectric effect?

Step 1: Understand that light can behave like a stream of particles called photons.
Step 2: Learn about the photoelectric effect, which is when light hits a metal surface and causes electrons to be ejected.
Step 3: Realize that for electrons to be ejected, the light must have a certain minimum energy, which is related to the frequency of the light.
Step 4: Recognize that if light were only a wave, it would not have this specific energy requirement, but since it behaves like particles, it does.
Step 5: Conclude that the photoelectric effect shows that light has a particle nature because it can transfer energy to electrons in a quantized way.
