There are a number of differences between longitudinal waves and transverse waves. Here is a list for easy reference:

  • In the case of longitudinal waves, the displacement of the medium is parallel to the direction of wave propagation. In the case of transverse waves, the displacement of the medium is perpendicular to the direction of wave propagation. Note that medium particles simply oscillate back and forth (for longitudinal waves) and up and down (for transverse waves).
  • Sound waves and P-waves of an earthquake are examples of longitudinal waves. Some common examples of transverse waves include S-waves of earthquakes, those generated on a string, etc. 
  • Longitudinal waves consists of compressions and rarefactions, whereas transverse waves consist of crests and troughs.
  • Longitudinal waves can take place in solids, liquids, and gases, while transverse waves can only take place in solids.
