If the pitch of sound is increased, what are the changes in the following?
a. the frequency
b. the wavelength
c. the wave velocity
d. the amplitude of the wave
Sound travels as waves and the pitch of sound is determined by the frequency of the waves. Therefore, if the pitch of sound is increased:
a. the frequency of the waves will increase
b. the wavelength of the waves will decrease
c. the wave velocity will remain constant as it depends on the medium through which the waves are traveling
d. the amplitude of the wave may or may not change, depending on the source of the sound and the manner in which it is produced.
