Quantam nature of light is explained by which of the following phenomenon
Text Solution
Verified by ExpertsThe correct answer is:
B
The quantum nature of light is best explained by the photoelectric effect.
Therefore, the correct answer is B.
- Photoelectric Effect: In this phenomenon, light can eject electrons from a metal surface when it is above a certain frequency threshold. This behavior supports the idea that light consists of particles called photons, each with quantized energy proportional to its frequency (E = hf, where h is Planck's constant and f is the frequency).
- Huygen's Wave Theory: This theory describes light as a wave and does not explain quantum phenomena.
- Maxwell's Electromagnetic Theory: While it describes light as an electromagnetic wave, it also doesn't incorporate quantum aspects.
- de-Broglie Theory: This pertains to the wave-particle duality of matter, which is secondary to the quantum nature established by the photoelectric effect.
Therefore, the correct answer is B.
