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.
A standing wave is also known as a stationary wave. It is a wave that remains in a constant position. This phenomenon can occur because the medium is moving in the opposite diâ¦rection to the wave, or it can arise in a stationary medium as a result of interference between two waves traveling in opposite directions.
