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
What is f n = 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 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
