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?

a. | The sound wave's frequency would increase. | b. | The sound
wave's energy would decrease. | c. | The sound wave's amplitude would be

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 more as more energy is transferred to your
surroundings | c. | Your mirror would shake less as the sound wave energy dissipates.
