A fighter jet moving at 1200 km/h barrels towards a thrilled crowd at a local air show. The engine produces a 3.500 kHz sound. (a) Determine the frequency the crowd perceives, taking the speed of sound as 342 m/s. (b) Calculate the frequency perceived if instead the jet maneuvers above the crowd, flying upwards away from it at the same speed.

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.
