In one place I read that since the particles are big they reflect white light as is. But in another I read that they are made up of water droplets of varying sizes so, small droplets: make blue medium droplets: make green larger droplets: make red ...and together they combine to make a white cloud. Which one is correct? And also, under Raman effect it's given that in Rayleigh scattering the scattered light is the same as that of the incident light. But how. The sky is blue. This is because blue light is scattered. But the incident light is white? Or do they mean that the scattered light's wavelength does not change?
