Q: Why is lightning seen before thunder is heard?

A: lightning seen before thunder is heard

Q: What happens to the wavelength of sound as the frequency decreases?

A: The wavelength of the sound is the ratio of the speed of the sound waves to their frequency. This…

Q: What is the difference between sound and hearing?

A: Sound is derived due to vibrations caused in a medium when an object produces vibration pressure…

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.
