SOUND I
COLLEGE PREPARATORY PHYSICS

TEXTBOOK: Chapter 13; pages 479 - 490.

OBJECTIVES:

Describe the origin of sound.
State the type of wave that sound is; describe what is oscillating in a sound wave; define compressions and rarefactions.
Relate pitch to frequency.
Identify the frequency range of audible sound; define infrasonic and ultrasonic.
If given a fundamental frequency, to be able to state the frequency one octave above or below it and the frequency two octaves above or below the fundamental frequency.
Compare the speed of sound in air to its speed in solids, liquids, and a vacuum.
Experimentally determine the speed of sound waves in air.
State the speed of sound in air at 0 degrees Celsius and compute its value at other temperatures.
Solve problems relating the frequency, wavelength, and velocity of sound waves.
Explain what is meant by the Doppler Effect and compute the frequency shift noticed for an approaching or receding sound source.
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.
