STANDING

Animation of Standing Wave

This animation shows how a standing wave is produced from the superposition of two waves.

At the top of the screen, two traveling sine waves are shown. They have the same wavelength but are traveling in opposite directions. At the bottom of the screen, the superposition of the two waves is shown. The result is a standing wave.
