Photoelectric Effect vs. Wave Model

Click For Summary
SUMMARY

The discussion centers on the limitations of the wave model of light in explaining the photoelectric effect. Key points include that the energy of ejected electrons is determined by the frequency of light, not its intensity, contradicting wave theory expectations. Additionally, electrons are ejected almost instantaneously, which would not occur under the wave model. These observations necessitate a quantum mechanical understanding of light, specifically the particle nature of photons.

PREREQUISITES
  • Understanding of the photoelectric effect
  • Familiarity with wave-particle duality
  • Basic knowledge of quantum mechanics

  • Explore the mathematical formulation of the photoelectric effect
  • Investigate the implications of wave-particle duality in modern physics
  • Review experimental evidence supporting the photoelectric effect
USEFUL FOR

Physics students, educators, and anyone interested in the fundamental principles of light and its interaction with matter.

What are some things about the photoelectric effect that can not be accounted for in the wave model of light?
 
Physics news on Phys.org
Too lazy to read wikipedia articles?
Or do you have a specific questions to the things mentioned there?

In addition, if you think of light as waves, a single electron would need ages to get enough energy to leave the metal.
 
The main puzzling fact is that the energy of the ejected electrons does not depend on the brightness of the light and in normal circumstances this is what we associate withe the energy of light.
Bright light means more energy.
The energy of ejected electrons depends on the colour(frequency) of the light and you would not normally associate this with energy.
Also electrons are ejected almost instantaneously and the should be a long time delay if the wave picture was true.
You will need to search 'Wiki!' to find a simple, consise explanation. Wiki is a good reference source but, in my opinion, it is not a good teaching source.
