Which phenomenon demonstrates the particle nature of light in the context of the photoelectric effect?
Correct Answer: Photoelectric effect
- Step 1: Understand that light can behave like a particle, called a photon.
- Step 2: Know that the photoelectric effect is when light hits a metal surface.
- Step 3: Realize that when light (photons) hits the metal, it can transfer energy to electrons in the metal.
- Step 4: If the energy from the photons is enough, it can knock the electrons out of the metal.
- Step 5: This emission of electrons shows that light has particle-like properties because it transfers energy in discrete packets (photons).
