huygens wave theory of light cannot explain

Explanation

Huygens's wave theory of light cannot explain the photoelectric effect (d). While the theory successfully explains other phenomena like diffraction, interference, and polarization, it fails to describe the particle-like behavior of light observed in the photoelectric effect.Here's why:Diffraction, interference, and polarization: Huygens's wave theory provides a good explanation for these phenomena. It explains how light waves interact with each other and with obstacles, producing observable effects like diffraction patterns, interference fringes, and the polarization of light waves.Photoelectric effect: This phenomenon demonstrates the particle-like nature of light. It observes that the energy of the ejected electrons from a metal surface depends on the frequency of the incident light, not its intensity. Huygens's wave theory, based solely on wave principles, cannot explain this dependence on frequency and the discrete nature of the ejected electrons.
