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

Clouds are white because light from the sun is white. As light passes through a cloud, it interacts with the water droplets, which are much bigger than the atmospheric particles that exist in the sky.
When sunlight reaches an atmospheric particle in the sky, blue light is scattered away more strongly than other colours, giving the impression that the sky is blue.
But in a cloud, sunlight is scattered by much larger water droplets. These scatter all colours almost equally meaning that the sunlight continues to remain white and so making the clouds appear white against the background of the blue sky.
