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.

Tutorial An earthquake occurs 7,375 km from a seismograph. The P-waves arrive 12.2 minutes later. How fast is the P-wave traveling (in km/s)? If the lag time between P- and S-waves is 10.6 minutes, how fast are the S-waves traveling (in km/s)? Using the shadow of S-waves you determine that the radius of the core is 55% of the Earth's 6,378-km radius. How many kilometers from the surface is this (in km)? Part 1 of 3 To calculate how fast the P-waves are traveling, we need to divide the distance the waves travel by the time. d Vp = Make sure you are dividing by the time in seconds. s Vp = Make sure you are dividing by the time in seconds. km/s
