Question

Why photoelectric effect cannot be explained on the basis of wave nature of light ? give reason

Answer 1

Answer:

Most commonly observed phenomena with light can be explained by waves. But the photoelectric effect suggested a particle nature for light. Then electrons too were found to exhibit dual natures. The Huygens' principle helped develop the wave theory of light and it was further developed by Fresnel and Kirchhoff.

Answer 2

Answer:

Wave nature of radiation cannot explain the following:

• The immediate ejection of photoelectrons.
• The presence of threshold frequency for a metal surface.
• The that kinetic energy of the emitted electrons is independent of the intensity of light and depends upon its frequency.

Thus, the Photoelectric effect cannot be explained on the basis of wave nature of light.
