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 $$\lambda $$₁ is produced at the lower end of the rope. The wavelength of the pulse when it reaches the top of the rope is $$\lambda $$₂. The ratio $$\lambda $$₂/$$\lambda $$₁ is

$$\sqrt {{{{m_2}} \over {{m_1}}}} $$

$$\sqrt {{{{m_1} + {m_2}} \over {{m_1}}}} $$

$$\sqrt {{{{m_1}} \over {{m_2}}}} $$

$$\sqrt {{{{m_1} + {m_2}} \over {{m_2}}}} $$
