Why the clouds are generally white in colour ?

Answers (1)

best_answer

The clouds are at much lower height. They are seen due to scattering of light due to lower parts of earth's atmosphere, which contains large dust particles, water droplets, ice particles etc. As the size of scatterer is much greater than the wavelength of light, Rayleigh scattering is not valid. Rather, all wavelengths are scattered nearly equally. tHerefore, all equally scattered colours merge to give us the sensation of white. Hence, clouds generally appear white.
