Unlike body waves, surface waves (also known as long waves, or simply L waves) move along the surface of the Earth. Surface waves are to blame for most of an earthquake's carnage. They move up and down the surface of the Earth, rocking the foundations of man-made structures. Surface waves are the slowest moving of all waves, which means they arrive the last.
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. Resonance â when a FORCED vibration matches an objectâs natural frequency thus producing vibration, sound, or even damage.
