Problem C15:
Consider the two vibrating strings shown below. They each have the same
tension T. One has a length L_{0}
and a mass m_{0}. This string is vibrating in its fundamental mode with
a frequency f_{0}. The second string has a mass of m=n_{1}m_{0}
and a length of L=n_{2}L_{0}. This string is vibrating in its
first harmonic, as shown, with a frequency of f=f_{0}/
√n_{3}.
what is n_{3}? Note that n_{1}, n_{2} and n_{3} are unitless.
