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.

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?
