Lab Five Standing Waves Purpose: In this lab, our goals are to understand how standing waves get set up on a string and how to explore the relationships between frequency, wavelength, tension and density. Also, our goal is to be able to measure the wave speed of a string. Data and Calculations : Part One: Total Unstretched Length of Elastic Cord 1.09 ± 0.005 meters Mass of Elastic Cord 0.00449 ± 0.0001 kilograms Stretched Length of Vibrated Section of Cord (L2) 1.25 ± 0.005 meters Unstretched Length Section of Vibrated Cord (L1) 0.973 ± 0.005 meters Mode (n) Frequency (Hz) Wavelength (meters) Tension (Newtons) 1 14.7 2.50 ± 0.005 4.090 2 29.4 1.25 ± 0.005 4.080 3 44.1 0.833 ± 0.005 4.079 4 58.0 0.625 ± 0.005 4.017 5 73.1 0.50 ± 0.005 4.012 6 87.1 .4166 ± 0.005 4.012 Part Two: Distance from Pluck Point to Vibrator Blade 1.25 ± 0.005 meters Earliest Possible Time for Decrease in Tension 0.564 Seconds Best Time for Decrease in Tension 0.566 Seconds Latest Possible Time for Decrease in Tension 0.570 Seconds Earliest Possible Time for Change in Voltage 0.602 Seconds Best Time for Change in Voltage 0.604 Seconds Latest Possible Time for Change in Voltage
