Question

why are clouds in white​

Answer 1

Answer:

When clouds are white (and many are not), “it’s because light from the sun is white, a combination of all the colors of the rainbow,” said Michael Kaufman, professor of physics and astronomy at San Jose State University in California. As light moves through the clouds, it is dispersed by water droplets. These are comparable to or bigger than the wavelengths of light, Dr. Kaufman said, and there are lot of droplets in the average cloud.

The result is that all the wavelengths are scattered more or less uniformly; to our eyes, no color predominates.
