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


v

2L

What is fn = n

B 500


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

Place A Wager

C 400


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.

F 400


What is an ultrasound?

F 400


___________ is transferred by waves and is determined by the _______________ of the wave.

F 500


What is energy, amplitude?

F 500
