After studying the material of this chapter, you should be able to:
1. Determine the speed of sound in air at one atmosphere of pressure at different temperatures.
2. Distinguish between the following terms: pitch, frequency, wavelength, sound intensity, loudness.
3. Determine intensity level in decibels of a sound if the intensity of the sound is given in W/m2.
4. Explain how a standing wave can be produced in a wind instrument open at both ends or closed at one end and calculate the frequencies produced by different harmonics of pipes of a given length.
5. Determine the beat frequency produced by two tuning forks of different frequencies.
6. Explain how an interference pattern can be produced by two sources of sound of the same wavelength separated by a distance d.
7. Solve problems involving two sources for m, d, λ, and the angular separation (θ) when the other quantities are given.
8. Solve for the frequency of the sound heard by a listener and the wavelength of the sound between a source and the listener when the frequency of the sound produced by the source and the velocity of both the source and the listener are given.
9. Explain how a shock wave can be produced and what is meant by the term "sonic boom."
