Answer
No standing wave created.
Work Step by Step
Using the formula $f_n=nf_1$ and finding $f_1$, the harmonic number can be found. Find $f_1$ using $$f_1=\frac{v}{2L}$$ Since $v=\sqrt{\frac{\tau}{\mu}}=\sqrt{\frac{1.00 \times 9.80}{0.0016}}=78.3$ m/s. Substituting velocity leaves $$f_1=\frac{78.3}{2(1.20)}=32.6 Hz$$ Finally, rearranging the equation $f_n=nf_1$ leaves $n=\frac{f_n}{f_1}$, or $$n=\frac{120}{32.6}\approx3.7$$ This is not close to a whole number, therefore, no harmonic is produced.
