Sound PRE Test
1. If you are attending a rock concert and the sound of the guitar is much louder than the
singer’s voice, which of the following conclusions would be most reasonable?
a) The guitar is producing sound waves of a longer wavelength than the singer’s
voice.
b) The singer is producing sound waves of a longer wavelength than the guitar’s
strumming.
c) The singer is producing sound waves of a higher amplitude than the guitar’s
strumming.
d) The guitar is producing sound waves of a higher amplitude than the singer’s
voice.
2. Dave’s sister is producing sound by banging cymbals together. How could she decrease the
loudness, or volume, of the sound the cymbals make?
a) increase the force she uses to bring the cymbals together
b) decrease the size of the cymbals
c) increase the size of the cymbals
d) decrease the force she uses to bring the cymbals together
3. Why do the thin strings on a guitar produce a sound with a higher pitch than the thick
strings on a guitar produce?
a) The thin strings vibrate faster than the thick strings.
b) The vibration of the thin strings is weaker than the thick strings.
c) The vibration of the thin strings is stronger than the thick strings.
d) The thin strings vibrate slower than the thick strings.
4. The graph below shows the relationship between pitch and vibration speed of sounds.
Which of the following can be concluded from the graph?
a) As the rate of vibration increases, pitch decreases.
b) The higher the vibration speed of a sound, the higher the pitch.
c) The pitch of a sound is not related to vibration.
d) All sounds have the same vibration speed.
5. Which of the following sounds would be produced by fast, weak vibrations?
a) high-pitched, loud sound
b) low-pitched, soft sound
c) high-pitched, soft sound
d) low-pitched, loud sound
6. Mr. Gibson measured the speed of sound in several different materials. His results are found
in the table below.
