Speed of Sound
Abstract: We used a function generator to measure the hertz of the first harmonic with both ends open. We needed to execute multiple calculations to make sure at the end of the experiment it will equal to 343 hz. The measure moments that were given was the length of the tub and the diameter of the tub and the frequence of the function generator. We ended up getting 343 hz after calculating the displacement.
Introduction: We are calculation a the standing waves in a pipe. To calculate that we would need to measure the pipe which was 1.52 meters. Then we measured the diameter which was .102 m. Then to get the freq with the function generator to the first harmonic with both ends open we started at 100 hz but we found the best representation …show more content…
Since landa equals 3 it would be constructive which is loud. Our hypothesis was that the final sound frequence would be 343 hz after all the calculations and taking the displacement. All our displacements were measured proportionally with in what could proportional human error. Error that could be consepted in this lab was the finding the beginning frequence or making a unit conversion issue as we wanted all the calculations to be in meters and centimeters. I learned you can find the final frequence by using all the variables give like the length of the tube and the diameter of the tube and the original frequence from the function generator. The most difficult part of this lab was making sure you were measuring the proper displacements for the variables given and human error. As in this unit of physics we have been studying simple harmonic motions and standing waves and lastly doppler and interference. All these topic have to do with waves and frequency. Our error or percent difference would be our displacement which turned out to be +-12.39 hz. Displacement of landa was the factor that we could be off .03 meters on measuring the diameter. As for the displacement we found that it could be within +- 3 hz so our equation for displacement factored that in …show more content…
In this lab we were testing that to see if it is true. We did that by using a function generation to run a frequence threw a plastic pvc pipe. Before we could find the final frequence we had to find the landa then we could find the final displacement. But that doesn’t end there because we have to find the displacement or margins for human error. When we summed up all the little measurements that could have be off properly we found the displacement was +- 12.39. So if add the 12.39 to the final frequence we got which was 331.36 which would equal to right around 343 hz which is the final frequence for first harmonic with both ends open. My results were actually what was expected for this lab if they were way off we would have to re address why they were like that. The most challenging part of this lab was that it was straight forward and you know if you did not get close to 343 hz you messed up somewhere along the way. If I could improve this lab I would make them try multiple attempts and measurements so we could get the displacement down to a smaller number. As 12 is not high but it could definitely be
