A string of length L is tied at both ends, and a harmonic mode is created with a frequency of fA. The next successive harmonic is at a frequency of fB. Note that the fundamental frequency is not necessarily fA. A) What is the speed of transverse waves on the string? Your answer should contain fA, fB and L. B) What is the number of antinodes of fA? In other words, what is n? Your answer should contain fA and fB.
