a. Choose an example of sound in your life and describe it in full physical terms:

1. what is the significance of this sound to you?
2. what object is oscillating to produce this sound?
3. what is this sound producing object's oscillation frequencyin hertz and resulting sound wavelengthin meters? (this page about audio frequency(Links to an external site.) may be useful)

b. Suppose you wanted to confirm Salviati's experiment measuring the speed of sound:

1. If you wanted a 2.00 s delay from sound production to reception and knowing Salviati's value for the speed of sound already, at what distance in meters would you need to place your telescope and sound-receiving pendulum from the sound-producing pendulum?
2. Note that the pendulums strike their sounding targets in 1/4 of their period. If the first (sound-producing) pendulum has a period of 0.50 s, what periodin secondswould the second (sound-receiving) pendulum need to have in order strike at the same time as the first pendulum sound arrives at the distance calculated in the previous question?
3. What would thelength of each pendulum bein meters in order to run this experiment?

c. Contemporary "concert pitch" defines the note A₄ as having the frequency 440 Hz. What wavelength of sound in meters does this produce?

d. A guitar string has a vibrating length of 0.348 m from its tuning nut to the bridge, and the vibrations travel along the screen at 427 m/s. What is the fundamental frequency (n=1)of the sound in hertz thatthe string produces?

e. In a few sentences, describe how the evidence for air pressure waves of compression and rarefaction as the phenomenon of sound.
