Part 1: a rope has one end tied to a vertical support. you hold the other end so that the rope is horizontal. if you move the end of the rope back and forth with a frequency of 4 hz, the transverse wave you produce has a wavelength of 0.5 m. what is the speed of the wave in the rope? a. 0.13 m/sb. 8 m/sc. 2 m/sd. 4 m/spart 2: a rope with a mass density of 1 kg/m has one end tied to a vertical support. you hold the other end so that the rope is horizontal and has a tension of 4 n. if you move the end of the rope back and forth, you produce a transverse wave in the rope with a wave speed of 2 m/s. if you double the amount of tension you exert on the rope, what is the wave speed? a. 2.8 m/sb. 1.0 m/sc. 2.0 m/sd. 0.25 m/se. 4.0 m/s
