Pump Up the Volume Potpourri
The property of a sound wave determines the perceived
pitch.
A 100
What is frequency?
A 100
The type of a mechanical wave since a sound wave is
propagated by the compression and rarefaction
of air.
A 200
What is longitudinal?
A 200
This solely determines the speed of sound.
A 300
What is the medium?
A 300
The property of air which primarily determines the
speed of sound.
A 400
What is temperature?
A 400
The property of the wave that doubles if the frequency is halved in a given medium.
A 500
What is wavelength?
A 500
Another term for the first harmonic.
B 100
What is the fundamental frequency?
B 100
On a vibrating string, these points experience no
displacement.
B 200
What are nodes?
B 200
This occurs when an object vibrates at its natural
frequency.
B 300
What is resonance?
B 300
The frequency of the third harmonic is this many times greater than that of the first
harmonic.
B 400
What is three?
B 400
The equation for the harmonic series of a pipe
open at both ends.
B 500
B 500
What is fn = n v 2L
This principle explains why the pitch produced by a
moving motorcycle changes as the motorcycle passes an
observer.
C 100
What is the Doppler Effect?
C 100
This behavior of a sound wave is responsible for
creating an echo.
C 200
What is reflection?
C 200
This behavior of a sound wave allows sound to bend
around small obstacles.
C 300
What is diffraction?
C 300
DAILY DOUBLE
C 400
DAILY DOUBLE
Place A Wager
The observable phenomenon that occurs when the wave
fronts generated by a rocket precisely align.
C 400
What is a sonic boom?
C 400
The number of beats heard per second when a 400 Hz
and a 403 Hz tone interfere.
C 500
What is 3?
C 500
The reciprocal of period.
D 100
What is frequency?
D 100
The point on a graph of a wave that specifies the
maximum positive displacement.
D 200
What is the crest?
D 200
The equation that relates wave speed to frequency and
wavelength.
D 300
What is v = f λ?
D 300
The units of the horizontal axis of a graph that specifies
the period of a wave.
D 400
What is seconds?
D 400
The frequency of a sound wave with wavelength 50 mm and a speed of sound of 343
m/s.
D 500
What is 6860 Hz?
D 500
This property of a sound wave determines how loud a
sound is perceived.
E 100
What is amplitude?
E 100
Describes the ratio of two intensities of sound.
E 200
What is a decibel?
E 200
If the decibel level of a sound increases by 10 dB, this
property increases by a factor of 10.
E 300
What is intensity?
E 300
The threshold of hearing for humans is this number of
decibels.
E 400
What is 0 dB?
E 400
A yodeler is yodeling in a valley. If the yodel takes
0.25 s to come back to him from one side and 0.5
seconds from the other, how wide is valley? (assume that
the speed of sound = 343 m/s).
E 500
What is 128.6 m?
E 500
In general, sound travels fastest through this phase of
matter.
F 100
What is a solid?
F 100
This part of a clarinet is responsible for producing the
sound due to its vibration.
F 200
What is the reed?
F 200
This part of a guitar is responsible both for the
source of the sound and the medium that carries the sound
wave.
F 300
What is the string?
F 300
A sound whose frequency is higher than can be heard by
humans. Also a medical technology used to observe a
fetus.
