Enter Competition

No. 4, Colour Code series

By Kym Cox ARPS

This photograph shows light interference patterns of a soap film. The film causes the light to diffract, in the same way a prism does. But, because the soap film is made of a liquid it is constantly being drained due to the force of gravity. Soap films are very thin, therefore the slightest change in air pressure will cause the liquid to move in different directions. To see the colourful interference patterns the studio light must be positioned at a certain angle.
