A uniform rope of length L and mass m1 hangs vertically from a rigid support. A block of mass m2 is attached to the free end of the rope. A transverse pulse of wavelength lamda 1 is produced at the lower end of the rope. The wavelength of the pulse when it reaches the top of the rope is lamda 2. The ratio (lamda 2)/(lamda 1) is
