Huygen's Principal: Practice Problem & Solution

Which one of the following phenomena is not explained by Huygen's construction of wavefront? (1988)
Refraction
Reflection
Diffraction
Origin of spectra

Short Solution (Best for NEET):

To solve this problem, we apply the core principles of Huygen's Principal. Understanding the underlying formula is key to arriving at the correct answer below:

Huygen's wave theory of light successfully explained phenomena like reflection, refraction, interference, and diffraction. However, it could not explain the origin of spectra, which requires quantum mechanics and the particle nature of light.
