Which phenomenon demonstrates the particle nature of light as evidenced 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 occurs when light hits a metal surface and causes electrons to be ejected.
Step 3: Realize that for the 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 be able to eject electrons in this way, especially if the light's frequency is below a certain threshold.
Step 5: Conclude that the photoelectric effect shows that light has particle-like properties, as it can transfer energy to electrons in discrete amounts.
