 * Notes**


 * 17.1 Mechanical Waves and Sound**

__Objectives__:

1. Define mechanical waves and relate waves to energy. 2. Describe transverse, longitudinal, and surface waves and discuss how they are produced. 3. Identify examples of transverse and longitudinal waves. 4. Analyze the motion of a medium as each kind of mechanical wave passes through it.


 * 17.2 Properties of Mechanical Waves**

__Objectives__:

1. Define frequency, period, wavelength, and wave speed and describe these properties for different kinds of waves. 2. Solve equations relating wave speed to wavelength and frequency or period. 3. Describe how to measure amplitude and relate amplitude to the energy of a wave.


 * 17.3 Behavior of Waves**

__Objectives__:

1. Describe how reflection, refraction, diffraction, and interference affect waves. 2. State a rule that explains refraction of a wave as it passes form one medium to another. 3. Identify factors that affect the amount of refraction, diffraction, or interference. 4. Distinguish between constructive and destructive interference and explain how standing waves form.


 * 17.4 Sound and Hearing**

__Objectives__:

1. Describe the properties of sound waves and explain how sound is produced and reproduced. 2. Describe how sound waves behave in applications such as ultrasound and music. 3. Explain how relative motion determines the frequency of sound an observer hears. 4. Analyze the functions of the main regions of the human ear.
