Question

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 λ₁ is produced at the lower end of the rope. The wavelength of the pulse when it reaches the top of the rope is λ₂ the ratio λ₂/λ₁ is(a) $\sqrt{\frac{m_{1}}{m_{2}}}$(b) $\sqrt{\frac{m_{1}+m_{2}}{m_{2}}}$(c) $\sqrt{\frac{m_{2}}{m_{1}}}$(d) $\sqrt{\frac{m_{1}+m_{2}}{m_{1}}}$
