MHT CET 2025 Physics question

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

(A)Different colours of light are due to different wavelengths of waves.
(B)Different colours of light are due to different sizes of the corpuscles.Correct
(C)Speed of light in denser medium is less than that in rarer medium.
(D)It can explain laws of reflection and refraction.

Answer: (B)

Solution

Huygens' wave theory treats light as a wave. In it, the colour of light is determined by its wavelength (and frequency), so statement (A) is correct. Wave theory predicts that light travels slower in a denser medium than in a rarer one, which is statement (C), and it explains
