Obviously they scatter light better than their surroundings -- why (Rayleigh scattering is only part of it)? Hint: estimate an upper limit on the size of a water drop in a cloud. What would you see as you looked at a cloud whose water drops were increasing in size through this limit? Steve Crandall mhuxt!evans
