Question

Why clouds appear white?

Answer 1

clouds r not white they appear white because of sun's Ray, we all know that the white light is made up of 7 colour and all 7 colour get absorb by the water vapor and dust particles and that's how they appear as white

Answer 2

The clouds are nearer the earth surface and they contain dust particles and aggregates of water molecules of size bigger than the wavelength of visible light.Therefore,the dust particles and tiny ice particles present in clouds scatter all the colours of incident white light from the sun to the same extent and hence, we could see the clouds white.
