Dear discuss-lfm members, <<DO your experiments>> 1. 90 deg scattering the blue sky is polarized. Look at the blue sky through a polaroid. How to get polaroid: Electronic calculator (Liquid crystal equipments) use polaroid. Take off! 2. Look at the rainbow through the polaroid. What a beautiful! Try it. 3. Half moon is scattering sunlight through 90 deg to you. Is the half moon light polarized? 4. What is Brewster's angle? Thanks Syu
