Atransverse sinusoidal wave is moving along a string in the positive direction of an x axis with a speed of 86 m/s. at t = 0, the string particle at x = 0 has a transverse displacement of 4.0 cm from its equilibrium position and is not moving. the maximum transverse speed of the string particle at x = 0 is 18 m/s. (a) what is the frequency of the wave? (b) what is the wavelength of the wave? if the wave equation is of the form y(x, t) = ym sin(kx ± ωt + φ), what are (c) ym, (d) k, (e) ω, (f) φ, and (g) the correct choice of sign in front of ω?
