PHY2061 R. D. Field Department of Physics chp38_9.doc University of Florida Traveling Waves A °wave± is a traveling disturbance that transports energy but not matter. Constructing Traveling Waves:To construct a wave with shape y = f(x)at time t = 0traveling to the right with speed vsimply make the replacement xxvt→−. Traveling Harmonic Waves:Harmonic waveshave the form y = A sin(kx)or y = Acos(kx)at time t = 0, where kis the "wave number"(k = 2π/λwhere λis the "wave length") and Ais the "amplitude". To construct an harmonic wave traveling to the right with speed
