Everyone knows about rainbows, but have you heard of Sun Dogs and ice halos, moonbows and glories? Atmospheric Optics is a fascinating site, dedicated to the beautiful results of sunshine with water droplets or ice crystals.
The site has some amazing photographs, some simple, some almost unbelievable. And although the optics/mathematics here is very involved, the basic physics of refraction and dispersion is relatively simple. it's incredible to think that such basic ingredients could combine to produce such beautiful and complex displays.
