Sir, I am Shaun job of class 10, I have a doubt regarding physics on the topic of optics, This is the question Sir, Why do clouds appear white? For us to see white light the light that goes into the clouds must exit as a whole, but we know that as clouds are basically water drops, they, must disperse the light and when It exits it should disperse even more , so we should see clouds in 7 colours,but that doesn't happen Please resolve the misconception Sir And once again, thank you for your time Shaun |
