Sound Lab Quiz

wavelength frequency

2 identical guitars play 2 different notes on the same string, but play them equally loudly. The two sound waves produced would differ in (mark all that apply) 1) Amplitude 2) Wavelength 3) Speed 4) Period 5) Frequency

Wavelength, Frequency

2 identical guitars play 2 different notes on the same string, but play them equally loudly. The two sound waves produced would differ in (mark all that apply) 1) Speed 2) Amplitude 3) Wavelength 4) Frequency 5) Period

Amplitude

2 identical guitars play the same note on the same string, but guitar A is played more loudly than guitar B. The two waves would differ in 1) Period 2) Frequency 3) Wavelength 4) Amplitude 5) Waveshape

F/2

A frequency that is not an overtone of the fundamental frequency F is 1) 4F 2) F/2 3) 2F 4) 3F

Waveshape

A piano and a guitar play the same note, the same loudness. The two waves would differ in 1) Period 2) Wavelength 3) Frequency 4) Amplitude 5) Waveshape

Waveshape

A piano and a guitar play the same note, the same loudness. The two waves would differ in 1) Amplitude 2) Waveshape 3) Wavelength 4) Frequency 5) Period

Resonance

A pure musical note causes a thin wooden panel nearby to vibrate with the same frequency. This is an example of 1) resonance 2) interference 3) diffraction 4) an overtone

Has a relatively long wavelength

A sound wave whose frequency is 50 Hz (compared to sound waves with frequencies of 1000 Hz, for example) 1) none of these 2) is very loud 3) has a relatively long wavelength 4) is very soft 5) has a relatively short wavelength

Has a relatively long wavelength

A sound wave whose frequency is 50 Hz (compared to sound waves with frequencies of 1000 Hz, for example) 1) none of these 2) is very soft 3) has a relatively long wavelength 4) has a relatively short wavelength 5) is very loud

Should half

As the frequency of a specific wave (sound, light, slinky at a fixed tension) is doubled, the wavelength (choose the BEST answer) 1) should half 2) should decrease 3) should double 4) should remain the same and speed should change instead 5) should increase 6) none of these

Wire

Sound travels better through 1) Air 2) String 3) Wolly Yarn 4) Wire

False

Sound waves are transverse waves 1) True 2) False

The same

Sound waves whose frequency is 300 Hz have a speed relative to sound waves in the same medium whose frequency is 600 Hz that is 1) four times as great 2) twice as great 3) the same 4) half as great

Twice as great at L2

Sound waves whose frequency is 300 Hz have a wavelength L1. Sound waves in the same medium have a frequency of 600 Hz and a wavelength L2. Compared to L2, L1 is... 1) half as great at L2 2) four times as great as L2 3) twice as great as L2 4) the same as L2

Energy

The greater the amplitude of a wave, the greater its 1) energy 2) frequency 3) speed 4) wavelength

Louder it is

The greater the decibel (dB) level of a sound wave, the 1) higher its frequency is 2) farther away its source is 3) longer its wavelength is 4) louder it is

Made 1/2 as long

To produce a sound wave 1 octave higher, the length of the string should be 1) Made 1/4 as long 2) Made longer 3) Made shorter 4) Made 4x as long 5) Made 2x as long 6) made 1/2 as long
