A uniform rope of length L and mass $\displaystyle \mathrm{m}_1$ hangs vertically from a rigid support. A block of mass $\displaystyle \mathrm{m}_2$ is attached to the free end of the rope. A transverse pulse of wavelength $\displaystyle \lambda_1$ is produced at the lower end of the rope. The wavelength of the pulse when it reaches the top of the rope is $\displaystyle \lambda_2$. The ratio $\displaystyle \lambda_2 / \lambda_1$ is :
