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.

Incorrect.
A sound wave is incident on a pool of fresh water (20°C). The sound enters the water perpendicularly and travels a distance of 0.448 m
before striking a 0.174-m-thick copper block lying on the bottom. The sound passes through the block, reflects from the bottom
surface of the block, and returns to the top of the water along the same path. How much time elapses between when the sound enters
and leaves the water? (Hint: Take the speed of sound to be 1482 m/s in water and 5010 m/s in copper.)
