[Figure 1] shows history.I graphs of two different points on a string as a wave pulse moves along the string. The blue curve is the historyr graph for the point at x = 1.0 cm, and the green curve is for the point at X = -3.{) cm. 1|.u"-.u"hst is the velocity (including the correct sign for its direction] of this wave? y (cm) x = -3.0 cm What is the velocity (including the correct sign for its direction) of this wave Express your answer with the appropriate units.
