Huygen's wave theory of light could not explain the phenomenon of :
- A interference
- B diffraction
- C rectilinear propagation of light
- D photoelectric effect
Answer & Solution
Correct Answer
(D) photoelectric effect
Step-by-step Solution
Detailed explanation
Huygen's theory treats light as a wave, which successfully explains phenomena like interference and diffraction. However, it cannot explain the photoelectric effect, as that requires light to be treated as discrete particles (photons) to account for threshold frequency and…
