Short Answer 
The process of creating a disturbance in a rope begins with flicking one end, causing a peak that triggers adjacent turns to move in a domino effect. This energy travels down the rope, creating a sequence of peaks and troughs while the restoring force of the rope’s elasticity helps maintain continuous motion, effectively transferring energy.
Step 1: Initial Disturbance
The process begins when you flick a rope or string, which disrupts the equilibrium position of the rope’s turns at one end. This action creates a “peak” or bulge in the rope, where the displaced turn begins to exhibit movement. As this energy is transferred, the neighboring turns also start to move up and down, causing a chain reaction throughout the rope.
Step 2: Propagation of Energy
As the displacement occurs, each turn in the rope acts like a domino, pushing and pulling its adjacent neighbor. This domino effect allows the initial disturbance to travel down the length of the rope without any single turn moving significantly. It is a coordinated motion where energy is passed along, continuously creating peaks and troughs sequentially as the pulse forms and advances.
Step 3: Restoring Force and Continued Motion
The restoring force of the rope’s elasticity comes into play as the displaced turns attempt to return to their original position. This recovery motion creates a trough following each peak, further driving the propagation of the disturbance. Consequently, new peaks and troughs continuously form, allowing the pulse to move forward along the rope, efficiently transferring energy from one turn to the next.
