A guitar player plucks two strings simultaneously. One string is tuned to a (fundamental) frequency of 381 Hz. It is found that beats are audible, with a beat frequency of 5.54 Hz. What are possible values for the frequency of the other string? (Answer the larger frequency first).

Answer 1

F = 381 +5.54 = 386.54
F = 381 - 5.54 = 375.46
