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?
