Characteristics of longitudinal wave

When particles of the medium vibrate about their mean position parallel to the direction of propagation of the disturbance, the wave is called longitudinal wave. When particles of the medium vibrate about their mean position parallel to the direction of propagation of the disturbance, the wave is called longitudinal wave.

Examples: The various examples of sound wave are: Sound wave, Waves in a slink, Glass vibrations, Ultra sound, Spring oscillations, Waves in a spring etc.

  • The wave in which the particles of the inanimate medium vibrate about their mean position to the direction of propagation of the disturbance, the wave is called the longitudinal wave.
  • During flow of the wave compression and rarefaction of the medium take place.
  • Distance between two successive compression or contraction or combined distance of a compression and a rarefaction is called wavelength.
  • Polarization of the medium does not take place.
  • This wave generates in elastic medium.
  • In longitudinal waves the displacement of the medium is parallel to the propagation of the wave.
  • For longitudinal wave the vibration of the particles of the medium are in the direction of wave propagation.
  • Examples of these waves are sound waves, tsunami waves, earthquake P waves, ultra sounds, vibrations in gas, and oscillations in spring, internal water waves, and waves in slink etc.
