vbottom=√(2mg/(m/l)) =√2gl
vtop=√(3mg/(m/l)) =√3gl
since f constant
=>√2gl /λ0=√3gl /λ
=> λ=√(3/2) λ0
A block of mass 2m is hanging at the lower end of a rope of mass m and length l . THe other end is fixed to the ceiling .A pulse of wavelength λ0 is produced at the lower end of the rope,what is the wavelength of the pulse when it reaches the top?
