A crude approximation of human voice production is to consider the breathing passages and mouth to be a resonating tube closed at one end. (See the figure) Part (a) What is the fundamental frequency, in hertz, of a voice if the tube is 0.24-m long, taking air temperature to be 37.0°C?

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?

(b) Discuss the limits this time resolution imposes on the ability of the sonar system to detect the size and shape of the object creating the echo.
