[VIDEO] RAYLEIGH SCATTERING explained by Professor Emeritus Walter Lewin at MIT (and more) For The Love Of Physics. I recommend watching the whole lecture from beginning, the part on color starts at about 28:00 http://youtu.be/SRh75B5iotI?t=27m56s
Rayleigh Scattering in the atmosphere - why the sky is blue
Next time a kid asks.. :)
Blue Sky and Rayleigh Scattering
why the sky is blue and clouds are white: Rayleigh scattering vs particulate (Mie) scattering
Rayleigh scattering: or why is sky blue
This experiment is perfect to help answer the classic kid question: "why is the sky blue?"
Setting up a Rayleigh Scattering Experiment
The Tyndall effect in opalescent glass: it appears blue from one side, but orange light shines through.
