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

Options:

  1. Diffraction
  2. Interference
  3. Emission of electrons
  4. Refraction

Correct Answer: Emission of electrons

Solution:

The photoelectric effect demonstrates the particle nature of light, as it shows that light can be thought of as consisting of particles (photons) that can impart energy to electrons.

Questions & Step-by-Step Solutions

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.
