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 to the free end of the rope. A transverse pulse of wavelength 0.06 m is produced at the lower end of the rope. What is the wavelength of the pulse when it reaches the top of the rope ?

A uniform rope of length L and mass m_(1) hangsvertically from a rigid support. A block of mass m_(2) is attached to the free end of the rope. A transverse pulse of wavelength lambda_(1) is produced at the lower end of the rope. The wavelength of the pules when it reaches the top of the rope is lambda_(2) . The ratio lambda_(2)//lambda_(1) is :
