Halliday, Resnick & Walker — Waves–I: Problem Problem_15

A stretched string has a mass per unit length of \(5.00 \text{ g/cm}\) and a tension of \(10.0 \text{ N}\). A sinusoidal wave on this string has an amplitude of \(0.12 \text{ mm}\) and a frequency of \(100 \text{ Hz}\) and is traveling in the negative direction of an \(x\) axis. If the wave equation is of the form \(y(x, t) = y_m \sin(kx \pm \omega t)\), what are (a) \(y_m\), (b) \(k\), (c) \(\omega\), and (d) the correct choice of sign in front of \(\omega\)?
