4. Use the data from your experiment to complete this data table. Provide data
for at least five trials (complete the experiment at least five times, using a
shorter length of string each time). Use the following formulas to help you
complete the table:

Time for 1 Wave Trip (s) = Time for 10 Wave Trips (s) / 10

Wave Speed (m/s) = String Length (m) / Time for 1 Wave Trip (s)
