A 7 m long uniform rope of mass 140 g is hanging freely from a ceiling. A transverse pulse is generated at the free end, which travels up to the top. Speed of wave (or pulse) along a string is given by v = √T/λ where T is tension along the string and λ is the linear density. Using = 10 ms2 , calculate the speed of the pulse at 5 different distances at every 1 m from free end.
Plot variation in the speed against the distance from the bottom. Using your graph determine the speed of the pulse at the midpoint of the string (indicate it on the graph provided in the answer sheet).
