Colloids are responsible for the blue colour of the sky and sea water.

1.	Colloids are responsible for the blue colour of the sky and sea water.(a) True(b) FalseThis question was posed to me during an interview.I'd like to ask this question from Surface Chemistry in chapter Surface Chemistry of Chemistry – Class 12
Answer» The correct ANSWER is (a) True Easiest explanation: There are a lot of suspended impurities in the atmosphere and sea water that act as COLLOIDS. DUE to Tyndall EFFECT and Rayleigh scattering, these colloidal particles SCATTER blue light and hence, make them appear blue in colour.
