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) Score Answer: String Length (m) Time for 10 Wave Trips (s) © 2007 K12 Inc.
