This picture shows a wave interference pattern created by two sources, visible in the upper right and bottom center around the brown duck. The feet of the duck create this interference pattern in the same way that interference occurs in a ripple tank. Nodes appear as calm lines of water due to destructive interference. Constructive interference causes the anti-nodes, which have larger troughs and peaks.
