Question 254: Wave Optics

Question

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

Accepted Answer

We are asked:
According to Huygen's wave theory of light, which one of the following statements is
not correct
?
Option A:
Different colours of light are due to different wavelengths of waves.
Ã¢ÂÂ Correct according to wave theory.
Option B:
Different colours of light are due to different sizes of the corpuscles.
Ã¢ÂÂ This belongs to NewtonÃ¢ÂÂs corpuscular theory,
not
HuygenÃ¢ÂÂs wave theory.
Option C:
Speed of light in denser medium is less than that in rarer medium.
Ã¢ÂÂ Correct prediction of HuygensÃ¢ÂÂ wave theory.
Option D:
It can explain laws of reflection and refraction.
Ã¢ÂÂ Correct.
Ã¢ÂÂ Correct Answer:
