the difference between transverse and longitudinal waves is the direction the medium of the wave moves in relation to the direction of wave propagation. in transverse waves, the medium is displaced perpendicular to the direction of the wave. in longitudinal waves, the medium is displaced parallel to the direction of the wave.read more≫

examples of longitudinal waves are sound waves in air and primary waves, known as p waves, in earthquakes. longitudinal waves are waves in which the displacement of particles occurs in parallel to the direction the wave travels. these waves are also called l-waves.read more≫

a longitudinal wave is made up of compressions and rarefactions. in compressions, the molecules of the wave are tightly compressed to form an area of high molecular density, while rarefactions have a low molecular density because the molecules are spread far apart.read more≫
