A wave on a string is the classic example of a transverse wave. Each part of the string moves up and down while the wave moves from side to side. Transverse waves can not happen in gases because the perpendicular motion is not created by any force. A Slinky is a great way to visualize longitudinal waves. Each part of the Slinky moves from side to side, just like the wave itself. Sound waves are longitudinal pressure waves in the air. Water waves involve a combination of transverse and longitudinal waves. The water moves up and down, but also back and forth.
