Chapter 16, Problem 22P

A sinusoidal wave is traveling on a string with speed 40 cm/s. The displacement of the particles of the string at x = 10 cm varies with time according to y = (5.0 cm) sin[1.0 − (4.0 s⁻¹)t].The linear density of the string is 4.0 g/cm. What are (a) the frequency and (b) the wavelength of the wave? If the wave equation is of the form y(x, t) = y_m sin(kx ± ωt), what are (c) y_m.(d) k, (e) ω, and (f) the correct choice of sign in front of ω? (g) What is the tension in the string?
