Emma - 10.01.2016 01:12The light from the sun looks white. But it is really made up of all the colors of the rainbow. Every color has its own wavelength. Since blue light is at the short wavelength end and air scatters short-wavelength light more than longer wavelengths, we see the sky as blue. (Attachment)
