Two waves are generated on a string of length 5.1 m to produce a three-loop standing wave with an amplitude of 5.0 cm. The wave speed is 119 m/s. Let the equation for one of the waves be of the form y(x, t) = ym sin (kx + ωt). In the equation for the other wave, what are (a) ym, (b) k, (c) ω, and (d) the sign in front of ω?
