The Speed of Sound/Waves Name: While King Report Date: Objective: To familiarize one with (a) what a wave is, (b) the characteristics of a wave (period, wavelength, frequency, amplitude, and velocity), and (how waves interact with each other. To differentiate between a transverse and a longitudinal wave. To examine the phenomenon of resonance as it applies to sound waves. To determine the speed of sound in the environment of the experiment. Preparation: Open up the website -> Air Column Resonance with Longitudinal Waves. Set Air Column Length to 0.5 [m]. Set Wavelength (theoretical wavelength) to 2.25 [m]. Procedure: Slowly increase the Air Column Length value until the first anti-nodal resonance for the constructed wave (in the second tube) is achieved at the end of the tube. Record this length. Increase the Air Column Length slowly until the second anti-nodal resonance is achieved at the end of the tube and record this value. Determine the difference in these values and record this as AL2,1. Increase the Air Column Length slowly until the third anti-nodal resonance is achieved (if possible) at the end of the tube and record this value. Determine the difference in the third and second Air Column Lengths and record this as AL3,2. Determine the average Air Column Length AL. The mean wavelength (experimental wavelength) can be determined using the formula lave = 2 ALave. Repeat the procedures for the Wavelength settings of 2.86, 3.03, 4.01, 4.33, and 4.43 [m]. Answer any questions to finalize the report and submit your results as a PDF in the Moodle lab link.
