If a wave travels through the same medium, which of the following must occur if the wavelength suddenly changes? O a O b O c Od The amplitude must change, since the medium would force the wave to adjust its size due to the wavelength change The frequency must change, because wave speed is constant so long as the wave is in the same medium The energy of the wave must change, since the energy of the wave is carried along the wavelength The wave must attempt to leave the medium, since waves cannot maintain a change in wavelength while in the same medium

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.
