The wave theory of light can not explain the phenomenon of
- A refraction of light
- B reflection of light
- C dispersion of light
- D Photoelectric effect
Answer & Solution
Correct Answer
(D) Photoelectric effect
Step-by-step Solution
Detailed explanation
Classic wave theory fails to explain the Photoelectric effect because it suggests that electron emission should depend on light intensity (brightness). In reality, it depends on a specific threshold frequency, proving that light behaves as discrete particles called photons…
