A sinusoidal transverse wave is traveling along astring in the negative direction of an x-axis. The figure shows aplot of the displacement as a function of position at time t=0; they-intercept is 4.0 cm. The string tension is 7.1N, and its linear density is 197.22 g/m. Find the Wavelength and wave speed.
