Many of the topics discussed in this chapter are useful beyond the topics of mechanical waves. It is hard to conceive of a mechanical wave with sharp corners, but you could encounter such a wave form in your digital electronics class, as shown below. This could be a signal from a device known as an analog to digital converter, in which a continuous voltage signal is converted into a discrete signal or a digital recording of sound. What is the result of the superposition of the two signals?
What is the difference between propagation speed and the frequency of a mechanical wave? Does one or both affect wavelength? If so, how?
(a) Seismographs measure the arrival times of earthquakes with a precision of 0.100 s. To get the distance to the epicenter of the quake, geologists compare the arrival times of S- and P-waves, which travel at different speeds. If S- and P-waves travel at 4.00 and 7.20 km/s, respectively, in the region considered, how precisely can the distance to the source of the earthquake be determined? (b) Seismic waves from underground detonations of nuclear bombs can be used to locate the test site and detect violations of test bans. Discuss whether your answer to (a) implies a serious limit to such detection. (Note also that the uncertainty is greater if there is an uncertainty in the propagation speeds of the S- and P-waves.)

During a fireworks show a rocket explodes above a listener 1km highwith respect to the ground while the sound produces 520watts of power.A group of people talking and they all produce sound levels of the samemagnitude at the listener’s position. The combined level when all fourtalks at once is 72dB. If a man is shouting producing SPL of 82dB and is160m away east side of the listener’s position; a. What is the sound intensity produced by the rocket explosion at the man’s position?b. Determine the sound intensity level of the man shouting at the group of people talking location when they are 120m away from the listener.c. Calculate the sound power produced by the individual four peopletalking.

Ever since seeing as shown in the previous chapter, you have been fascinated with the hearing response in humans. You have set up an apparatus that allows you to determine your own threshold of hearing as a function of frequency. After performing the experiment and recording the results, you graph the results, which look like as shown. You are intrigued by the two dips in the curve at the right-hand side of the graph. You measure carefully and find that the minimum values of these dips occur at 3 800 Hz and 11 500 Hz. Performing some online research, you discover that the outer canal of the human ear can be modeled as an air columnopen at the outer end and closed at the inner end by the eardrum. You use this information to determine the length of the outer canal in your ear.
