Summary Author: Denis Huber; Jim Foster

Rainbows are caused by reflection, refraction and dispersion of light by water drops and droplets, resulting in a strip of spectral colors across the sky, taking the form of a circular arc. You can also see rainbows near fountains and waterfalls, as in the case above at Val-d'Isère, France. This particular bow is from the light of the moon the night of August 6, 2020.
