Standing wave formation. Diagram illustrating how a standing wave (black) is formed by the addition of a wave (green) and its reflection (red) inside an oscillator. At fixed points the standing wave has no amplitude. These points are called nodes and their positions are shown by the grey vertical lines. Anti-nodes are the points of maximum amplitude or displacement. Standing waves like these are set up in musical instruments. For wind instruments, the waves represent compression rather than displacement.
