Question: One end of a horizontal rope is attached to a prong of an electrically driven tuning fork that vibrates the rope transversely at 120 Hz. The other end passes over a pulley and supports a 1.5D-kg mass. The linear mass density of the rope is 0.0550 kg/m.
(a) What is the speed of a transverse wave on the rope?
(b) What is the wavelength?
(c) How would your answers to parts (a) and (b) change if the mass were increased to 3.00 kg?
