Rayleigh Scattering

• Scattering, continued:
• Why is the sky blue?
• It's because of Rayleigh scattering - the selective scattering of the shorter wavelengths of visible light (violet and blue) by atmospheric gases.
• Note that Rayleigh scattering involves much smaller scattering particles than Mie scattering
• if there were no atmosphere, what color would the sun look like?
