Science sound Flashcards
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
Amplitude
A sound wave whose frequency is 50 Hz (compared to sound waves with frequencies of 1000 Hz, for example)
has a relatively long wavelength
The greater the amplitude of a wave, the greater its
Energy
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…
twice as great as L2
Sound waves are transverse waves
False
The greater the decibel (dB) level of a sound wave, th
Louder it is
As the wavelength of a specific wave (sound, light, slinky at a fixed tension) is doubled, the frequency (choose the BEST answer)
Should half
A frequency that is not an overtone of the fundamental frequency F is
F/2
A piano and a guitar play the same note, the same loudness. The two waves would differ in
Waveshape
As the frequency of a specific wave (sound, light, slinky at a fixed tension) is doubled, the wavelength (choose the BEST answer)
Should half
Sound travels better through
Wire
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
The same
A pure musical note causes a thin wooden panel nearby to vibrate with the same frequency. This is an example of
resonance
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)
wavelength, period, frequency
To produce a sound wave 1 octave higher, the length of the string should be
Made 1/2 as long
