A nylon guitar string has a linear density of $7\mathrm{.}94\frac{g}{m}$ and is under a tension of $161$ N $.$ The fixed supports are $D=94\mathrm{.}2cm$ apart. The string is oscillating in the standing wave pattern shown in the figure. Calculate the $($a$)$ speed, $($b$)$ wavelength, and $($c$)$ frequency of the traveling waves whose superposition gives this standing wave.
