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.

Question

Physics 20: SUMMER Assignment 14
9. An ambulance is driving away from you in an area with a speed limit of 50 km/h. You
measure the frequency of one of its siren tones to be 737 Hz, when you know the actual
frequency of the tone to be 770 Hz. The temperature outside is 13°C. Use the formula
below to approximate the speed of sound in that temperature, then determine if the
ambulance was speeding. Show all your work, including your rearranging of the Doppler
equation.

Each of the diagrams below represents a snapshot of two springs at an instant after a pulse has reached the boundary between them. The linear mass density, µ, is greater for the tightly coiled spring than for the other spring. Each diagram may contain flaws that would not be observed with real springs. For each diagram: a. Determine whether there is a flaw. If there is a flaw, describe it (a single flaw is sufficient) and continue to the next diagram. If there are no flaws, answer parts b and c. b. Make a sketch that shows the shape, width, and direction of motion of the incident pulse. c. Determine which pulse is the reflected pulse and which is the transmitted pulse.
