Question

Which one of the following phenomena is NOT explained by Huygens’ construction of wavefront?

G1 Physics · Accepted Answer

Step 1: Huygens construction treats every point of a wavefront as source of secondary wavelets. Step 2: This explains wavefront propagation, reflection, refraction and diffraction qualitatively. Step 3: Detailed origin of atomic line spectra requires quantized energy transitions, not Huygens construction. Final answer: (D) Origin of spectra.
