Question
When human vocal cords are used to sing "falsetto", the result is a very pure sound, consisting of only the fundamental frequency. Assume two singers are singing falsetto, producing a note with frequency 4063 Hz and a beat frequency of 4.5 Hz.
a. By how many hertz is the frequency of the sound produced by the lower note lower than the frequency of the combined sound?
b. By how many hertz is the frequency of the sound produced by the higher note higher than the frequency of the combined sound?
