Optics
September 2008
Crepuscular Rays, Heiligenschein, Iridescence? Do any of these terms ring a bell?
They all fall under the category of "Atmospheric Optics". When sunlight enters the atmosphere it is either scattered, absorbed, reflected or transmitted on through. How objects at the surface respond to this energy depends on their general nature and the wavelength that strikes them. Thus the world of Atmospheric Optics which you and I can enjoy.
