Homework Statement
A rope of mass m is hanging down from the ceiling. Nothing is attached to the loose end of the rope. As a transverse wave travels upward on the rope, does the speed of the wave increase, decrease, or remain the same?
Homework Equations
$$v=\sqrt{\frac{F}{m/L}}$$
$$F=-ma$$
The Attempt at a Solution
As the wave travels upward, the second equation would imply that the force on the wire directed downwards (i.e. gravitational force) is larger, so the speed would be smaller than if you did the same thing when standing high and the rope was attached to the floor. But the answer given in the book is "Increases". Why?
