:Calculate the speed of the wave using the time,
it takes to travel along the rope. Rope's length,
is measured using the meter stick.
-Attach one end of rope to a wall or post, shake from the unfixed end to generate a pulse. Measure the the time it takes for the pulse to reach the wall once it starts traveling using the stopwatch.
-Speed of the pulse can then be obtained as:

: Apply force of known value to the rope then use the following relation equation to find the speed of a pulse that travels on the rope.

-Use the measuring stick and measuring scale to determine
values of the rope then obtain
.
-Use the force measuring constant to determine
. These values can the be substituted in
to obtain
