The photoelectric effect demonstrates which nature of light?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is Option 2 i.e. Particle nature.
The photoelectric effect demonstrates the particle nature of light. This phenomenon occurs when light incident on a material ejects electrons from its surface, which can be explained by considering light as being composed of discrete packets of energy called photons.
The energy of these photons is directly proportional to their frequency, as described by Albert Einstein in 1905, supporting the idea that light exhibits particle-like behaviour.
