According to Huygen's wave theory of light, which one of the following statements is not correct?

Huygen's wave theory postulates that light propagates as waves rather than particles. Statement B is inconsistent with this theory as it attributes color differences to "sizes of corpuscles," a concept from Newton's corpuscular theory rather than wave theory.

Statement A aligns with wave theory, as different wavelengths correspond to different colors of light. Statement C is a key prediction of Huygen's theory: light travels slower in denser media than in rarer media. Statement D reflects the theory's success in deriving the laws of reflection and refraction.

The statement not correct according to Huygen's wave theory is B.
