Increase the frequency of the sound (you might want to turn the amplitude a bit lower first!). What happens to the movement of the speaker? What happens to the sound that the speaker makes? What happens to the wave that the speaker makes?

Step 1
This reduces the loudness of the sound produced by the speaker, making it more comfortable to listen to while you adjust the frequency. Show more…

(a) If the pitch of sound is increased, what are the changes in the frequency? Frequency will increase. Frequency will decrease. Frequency will remain the same. (b) If the pitch of sound is increased, what are the changes in the wavelength? Wavelength will remain the same. Wavelength will increase. Wavelength will decrease. (c) If the pitch of sound is increased, what are the changes in the wave velocity? Wave velocity will increase. Wave velocity will decrease. Wave velocity will remain the same. (d) If the pitch of sound is increased, what are the changes in the amplitude of the wave? Amplitude will increase. Amplitude will decrease. Amplitude will remain the same.

You use a set of speakers to play music at your 4th of July party. If a particular sound is emitted at a specific frequency and the intensity of the wave is doubled, how does the speed of the wave change? No answer text provided: There is no change in the speed of the wave as it depends on the medium. The speed will be reduced by two as it is indirectly proportional. The speed of the wave slowly dissipates. It will cause the amplitude to double, so the speed increases by four. The speed will double as it is directly proportional.
