TEXTBOOK:  Chapter 14; Section 14.1 to 14.6;  pages 442 - 457.

OBJECTIVES:

• Describe the origin of the sound in various musical instruments.

• State the type of wave that sound is and define compression and rarefaction. 

• Distinguish between audible sound, infrasonic sound, and ultrasonic sound.  

• Experimentally determine the speed of sound waves in air.

• State the speed of sound in air at 0 deg C and compute its value at temperatures near normal room temperature.

• Solve problems relating to the frequency, wavelength, and velocity of sound waves.

• Determine the frequency and the peak voltage of a vibrating source by using an oscilloscope.

• Differentiate between loudness and intensity.

• State the scale used to measure intensity and describe it. 

• Calculate the relative intensities of two sounds using the above scale.

• Explain what is meant by the Doppler Effect; calculate the frequency shift for an approaching or receding sound source.

• Describe how the Doppler effect relates to the blue and red shifts for light. 

• Describe the conditions for a sonic boom to be heard.
