A rope of total mass m and length L is suspended vertically. Analysis shows that for a short transverse pulse, the wave above a short distance from the free end of the rope can be represented to a good approximation by the linear wave equation.
Show that a transverse pulse travels the length of the rope in a time interval that is given approximately by . Suggestion: First find an expression for the wave speed at any point a distance x from the lower end by considering the rope's tension as resulting from the weight segment below that point.
