Standing Waves A standing wave is produced when a wave that is traveling is reflected back upon itself. There are two main parts to a standing wave: Antinodes â Areas of MAXIMUM AMPLITUDE Nodes â Areas of ZERO AMPLITUDE. Sound Waves Sound Waves are a common type of standing wave as they are caused by RESONANCE.
