August photograph by Flavia Jager Williams

Flavia Jager Williams says she's not a professional photographer, but always has her camera on her and is always looking for interesting things to photograph–such as this rainbow near Binda in the Southern Tablelands, New South Wales.

Rainbows are formed when sunlight is refracted (bent) and reflected while passing through raindrops in the atmosphere. Blue light refracts more than red, resulting in the separation of the colours. A rainbow is an optical phenomenon, and is specific to the viewpoint of the observer. It is not possible to reach the end of the rainbow–as you move towards it, the location will appear to change.
