A unifrom rope of length L and mass `m_(1)` hangs vertically from a rigid support. A block of mass `m_(1)` is attched 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)` ia

A

`sqrt((m_(1))/(m_(2))`

B

`sqrt((m_(1)+m_(2))/(m_(2)))`

C

`sqrt((m_(2))/(m_(2)))`

D
