Goals: The main goal was to determine if the speed of sound is a function of the frequency of the sound, secondly to further our study on standing waves and resonance. Procedure: The procedure can be found in the Physics Lab II Manual for COOP 2009, pages 49 – 52.

Analysis: The uncertainties for the frequency were reading uncertainties; they were determined by how much the frequency was altering on the wave generator. This number was chosen to be 2 Hz. The uncertainty in the length was a reading uncertainty from the meter stick; this was determined to be 1cm. The uncertainty for velocity was calculated using the high low method. Sample Calculations: Velocity: Uncertainty high/low: Percent difference: Wave Length: Deviation from average:
Results and Tables:

Conclusion: Summary of results: The velocity of sound is not independent of the frequency of the sound. The resonance of a frequency can be noticed by a change sound
