What limitation does the wave model of light have, as highlighted by Young's experiment?.
- A.It cannot explain the photoelectric effect.
- B.It fails to account for light's speed.
- C.It does not describe light's polarization.
- D.It cannot explain diffraction patterns.
Model answer
What a good answer should say
- It cannot explain the photoelectric effect.
Explanation
Why this works
A limitation of the wave model of light, as highlighted by Young's experiment, is that it cannot explain the photoelectric effect. While the wave model accounts for interference and diffraction, it fails to address phenomena where light behaves as a particle, such as the emission of electrons from a material.
This limitation underscores the necessity of a dual model of light, incorporating both wave and particle characteristics.
