The colour of sky is due to
- A transmission of light
- B wavelength of scattered light
- C absorption of light by atomspheric gases
- D All of the above
Answer & Solution
Correct Answer
(B) wavelength of scattered light
Step-by-step Solution
Detailed explanation
The blue colour of sky is due to Tyndall effect the colloidal particles absorb light, become self luminous and then scatter light of different wavelengths in all possible directions.
