1
If the wave shown is a sound wave shown, what are the correct labels for areas X and Z?
X = crest, Z = trough
X = trough, Z = crest
X = compression, Z = rarefaction
X = rarefaction, Z = compression
2
Through which medium does sound travel slowest?
all of the above
liquid
gas
solid
3
A longitudinal wave is different from a transverse wave because ―
particles move parallel to the path of the wave instead of perpendicular
energy is lost by the wave.
energy is transferred from the wave.
it has a longer wavelength.
4
What type of wave is shown?
a longitudinal sound wave
a fixed frequency sound wave
a variable frequency electromagnetic wave
a longitudinal electromagnetic wave
5
What effect causes musical instruments to produce sound?
resonance
wind
magnitude
harmony
6
If an observer encounters more waves while moving toward a wave source, what will the observer perceive?
a lower frequency
a lower pitch
the same frequency
a higher frequency
7
What two things affect the speed of sound?
the medium that the sound travels through and the temperature of the medium
the temperature and the mass of the medium that the sound travels through
the distance to the medium that the sound travels and the size of the wave
the compression and rarefaction of the sound waves
8
A string is vibrating and producing sound. What would happen to the sound if the vibrating string were longer?
The sound would stop.
The pitch of the sound would be higher
The sound would be louder.
The pitch of the sound would be lower.
9
Which is a tool that uses sound to find objects in a liquid?
laser
sonar
radar
doppler
10
Sounds are unable to travel through which of the following?
empty space
plasmas
liquids and solids
gases and liquids
11
An object vibrates at a certain frequency. A second object is forced to vibrate at the same frequency. This is called —
resonance
harmonics
amplitude
frequency
12
In which medium does sound travel fastest?
solid
plasma
liquid
gas
13
As sound waves travel through air, they cause air molecules to ―
vibrate
lose energy.
bend
be absorbed.
14
Sound waves are different from water waves because ―
sound waves travel in straight lines.
they have different wavelengths.
water waves are higher in frequency.
water waves are mostly transverse, but sound waves are longitudinal.
