Question

The main drawback of Huygens' theory was

• A. Failed to explain the rectilinear propagation of light
• B. Failed to explain the spectrum of white light
• C. Failed to explain the reflection of light wave
• D. Failed to explain the phenomenon of diffraction of light

Answer 1

The correct option is A Failed to explain the rectilinear propagation of light

The main drawback of Huygens' theory was that it failed to explain the rectilinear propagation of light.
It also failed to explain photoelectric effect, Compton effect.

Hence, option $\left(\text{A}\right)$ is correct.
