A sound wave in air or any gas is     A  movement of air back and forth perpendicular to  its direction of motion as the air flows at the speed of sound away from its source. A air molecule travels at the speed of sound wiggling up and down as it  goes along.     A vibration within  the air molecules  at the frequency of the sound     A propagating compression in air followed by a "rarefaction" when the density drops, with the denser regions separated by a wavelength.  The air molecules  on average do not move.     A  movement of air back and forth over a wavelength along its direction of motion as the air flows at the speed of sound away from its source. An air molecule travels with the speed of sound, wiggling to  and from as it goes along.

Shock Waves

Shock waves are common in continuum mechanics, and their dominance is attributable to the fact that they are stronger (or even less) compressible. Substantial perturbations propagated as sudden dynamic changes of a compressible medium supersonically. Shock waves are all around us in our daily lives. Lightning, earthquakes, volcanic eruptions, and meteorite impact all produce them in nature. Even the earth, which is protected by its magnetic field, generates a shock wave as in solar wind that travels around 20 Earth radiuses. These shock waves might be either constant, linked to the body, or unsteady, i.e., moving around with time. All of the shocks mentioned above can be damaging, so precautions must be taken to reduce their impact.
