An all female guitar septet is getting ready to go on stage. The lead guitarist, Kira,who is always in tune, plucks her low E string and the other six members, sequentially, do the same. Each member records the initial beat frequency between her low E string and Kira's low E string.
To tune an instrument using beats, more information than just the beat frequency is needed. In addition to recording the initial beat frequency , each member, except Diane, also records the change in the frequency (increase or decrease) when they increase the tension in their low E string.
Rank each member on the basis of the initial frequency of their low E string.
Rank from largest to smallest. To rank items as equivalent, overlap them.
Aiko=3Hz, fbeat increases
Chandra=1Hz fbeat decreases
Evita=5Hz fbeat decreases.
Freja=3Hz fbeat decreases.
Buffy=4Hz fbeat increases.
