Question - A stretched string has a mass per unit length of 5.00 g/cm and a tension of 10.0 N. A sinusoidal wave on this string has an amplitude of 0.12 mm and a frequency of 100 Hz and is traveling in the negative direction of an x axis. If the wave equation is of the form y(x, t) = ymsin(kx±ωt), what are (a) ym, (b) k, (c) ω, and (d) the correct choice of sign in front of ω?
