15. We write the string displacement in the form y = y m sin( kx + ωt ). The plus sign is used since the wave is traveling in the negative x direction. The frequency is f = 100 Hz, so the angular frequency is ω =2 πf =2 π (100 Hz) = 628 rad / s. The wave speed is given by v = p τ/µ ,where τ is the tension in the string and µ is the linear mass density of the string, so the wavelength is
