If you press down on a piano key, let's say middle C, it generates a sound
wave. Now, imagine that you press it down much harder so that it still plays the same tone but more
loudly. How would pressing the key down harder
change the sound wave produced?a. | The sound wave's wavelength would increase. | b. | The sound
wave's frequency would increase. | c. | The sound wave's amplitude would be
larger. | d. | The sound wave's energy would decrease. |

To play high pitch notes on a guitar, a musician must decrease the length of the
strings by pressing down on the strings with his or her fingers as they are being plucked or
strummed. Now imagine that a guitar string is cut into
four pieces of different lengths as shown below. Each piece is stretched between two supports
to the same tightness.
If each piece was plucked in the middle with the exact same amount of
force, which of the pieces would have the highest number of wave oscillations during one
second?

You are in your car waiting for the light to turn green at a traffic light. You
hear loud music coming from the car in the next lane. The music is loud enough that you can see your
rearview mirror shaking. What would happen to your rearview mirror
if the amplitude of the sound waves from the other car was increased?a. | Your mirror would shake at varying rates, faster and then slower. Then it would
stop. | b. | Your mirror would shake less as the sound wave energy dissipates.
| c. | Your mirror would shake more as more energy is transferred to your
surroundings | d. | Your mirror would shake more as less energy is transferred to your
surroundings. |
