Longitudinal waves Transverse waves Particles vibrate in a direction parallel to the direction of propagation of waves. Formed on the surface of solids and liquids. Compression and rarefactions are formed. Crests and troughs are formed. Longitudinal waves are those waves in which particles vibrate parallel to the propagation of the waves. In case of transverse waves, the particles vibrate perpendicular to direction of propagation of the wave.
