354876 A uniform rope of length \(12\;m\) and mass \(6\;kg\) hangs vertically from a rigid support. A block of mass \(2\;kg\) is attached at the free end of the rope. A transverse pulse of wavelength \(0.06\;m\) is produced at the lower end of the rope. The wavelength of the pulse when it reaches the top of the rope is
