Blue colour of the sky is due to
- A reflection of light
- B refraction of light
- C diffraction of light
- D scattering of light
Answer & Solution
Correct Answer
(D) scattering of light
Step-by-step Solution
Detailed explanation
Blue colour of the sky is due to scattering of light. Scattering \(\propto \frac{1}{\lambda^4}\) and \(\lambda\) is least for blue colour among the fundamental colour red, green and blue. So blue colour of light scattered the most. Therefore sky appear blue.
