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? propagated by the compression and rarefaction of air.

A 200

This solely determines the speed of sound. propagated by the compression and rarefaction of air.

A 300

What is the medium? propagated by the compression and rarefaction of air.

A 300

What is temperature? sound.

A 400

What is wavelength? halved in a given medium.

A 500

Another term for the first harmonic. halved in a given medium.

B 100

What is the fundamental frequency? halved in a given medium.

B 100

What are nodes? displacement.

B 200

B 300

What is resonance? frequency.

B 300

The frequency of the third harmonic is this many times greater than that of the first harmonic.

B 400

What is three? greater than that of the first harmonic.

B 400

v ends.

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? motorcycle changes as the motorcycle passes an observer.

C 100

C 400

The observable phenomenon that occurs when the wave fronts generated by a rocket precisely align.

C 400

What is a sonic boom? generated by a rocket precisely align.

C 400

What is 3? Hz tone interfere.

C 500

The reciprocal of period. Hz tone interfere.

D 100

What is frequency? Hz tone interfere.

D 100

What is the crest? positive displacement.

D 200

D 300

What is v = f λ? wavelength.

D 300

What is seconds? the period of a wave.

D 400

What is 6860 Hz? speed of sound of 343 m/s.

E 100

What is amplitude? perceived.

E 100

E 200

What is a decibel? perceived.

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? property increases by a factor of 10.

E 300

E 400

What is 0 dB? decibels.

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? 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 a solid? matter.

F 100

What is the reed? sound due to its vibration.

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? the sound and the medium that carries the sound wave.

F 300

A sound whose frequency is higher than can be heard by humans. Also a medical technology used to observe a fetus.
