Speed Of Sound Lab Possible Errors
This would have influenced the harmonic number at each given frequency, so the results would have been significantly varied. 3.

Speed Of Sound Lab Possible Errors
A spring constant k = 8.75 N/m. Drakkith, Jun 8, 2011 Jun 8, 2011 #7 n3w ton The percent margin was 10%, and yes 2 sig digs were used for all measurements. Found the antinode. 4.
- Also, there were many other sounds in the room which could have led to a different interpretation of the ideal sound.ArtifactReflectionThis lab helped me find the velocity of sound waves in

- The friendliest, high quality science and math community on the planet!
- We hypothesized that resonance would increase as frequency increased, and therefore a linear, increasing graph would be produced for number of antinodes and length.

- We stretched out the mass to start the oscillation.
- We repeated this several times, each time adding progressively more masses.
- Found the antinode. 4.
PC oscilloscope and storage is a better method. The friendliest, high quality science and math community on the planet! This could be due to measurment devices not being accurate enough or something like that. Resonance In Closed Air Columns Lab Sources Of Error This could be avoided by making sure that any background noise should be kept to a minimum.
The system returned: (22) Invalid argument The remote host or network may be down. Speed Of Sound Error Analysis So for I have:- One possible source of error could be in the recording of data and in the plotting of the graph. So for I have:- One possible source of error could be in the recording of data and in the plotting of the graph. We neglected to take into account the mass of the spring itself.
ResultsAs previously mentioned, the actual experiment consisted of setting the oscilloscope to single-trace mode, standing beside one microphone, and clapping. Resonance Lab Sources Of Error Due to budget cutbacks, all of our meter sticks were shortened 15%.... Why is this lab important? water level is never straight which can cause fluctuations in the waves enhancements, 1.
Speed Of Sound Error Analysis
Sarah and Caroline Objectives: What is the relationship between frequency and the tension of transverse waves traveling in a stretched string?What is the relationship between frequency and harmonic number?What is the Measure the diameter of the resonance tube (d) and record. 9. Speed Of Sound Lab Possible Errors the relationship between frequency and harmonic number is linear. Sources Of Error In Resonance Tube Experiment For example, what is the effect of a 0.5 degree shift in temperature?
Why is the time for more than one period measured? this content This was repeated while standing by the other microphone.

Therefore, the mass of the person causes the system to oscillate, and therefore corresponds mass with the k value. Tuning Fork Lab Sources Of Error
My students have suggested 1) There is the potential that the humidity in the tube be affecting the speed pf sound, but that is an issue only if you are thinking How did you determine that the speed of sounds in your air was 329 m/s? Our graph should show a linear relationship between length and the number of nodes. http://nzbsites.com/sources-of/possible-errors-in-titration-lab.html When graphing the second values of oscillation, we used the power fit for the trend line so that we could limit error because without using this fit, the slope value would
Hypothesis: Both of the spring constants that we find should be the same. Sources Of Error In Standing Waves Experiment The difference between the two is only .08 - fairly small as far as this experiment is concerned.The percent difference in the fundamental frequency was a mere 0.83%. tension graph): percent difference (between wavelengths solved for) percent error (exponent in frequency vs.
We also were trying to determine the speed of sound from our wavelength and frequency results.
If this frequency was off, the velocity we obtained from the graph would be slightly off. You will need this to calculate the actual speed of sound at that temperature. Conclusion The point of this lab was to find the spring force constant of the spring that we were using through two different methods and comparing them. Speed Of Sound Physics Lab Sources Of Error Share this thread via Reddit, Google+, Twitter, or Facebook Have something to add?
That's 20 degrees (shown as θ in figure 2).The mis-positioning would increase the distance to the near microphone by a ratio of 1/cos(θ), while the distance to the far microphone would Log in with Facebook Log in with Twitter Your name or email address: Do you already have an account? We found that the percent difference between these values is 1.88%, so therefore, we got a very low percent error, although we still did get some. http://nzbsites.com/sources-of/errors-in-calorimetry-lab.html What is the effect of a 1% change in pressure?
This could likely be attributed to rounding errors when doing calculations. Though the mathematical view to this lab is not such a deal. Show your calculations!Answer: The tube has a length of 0.350 m. The assembly was held onto the table with a clamp the prevent moving.
Rounding to 3 digits and applying our previously computed error bar of +4.2% to -7.2%, we obtain the value and error range of: Speed of Sound = 352 +15/-25 meters/secondor an Of course other errors can be taken into account such that the error in measuring the room temperature which is at least 0.5 degree Celsius. Show also how the length of the tube L5,is related to the wavelength, λ.()()( The parentheses each represent 1/4 of a wavelength for a closed tube. You can only upload files of type PNG, JPG, or JPEG.
We had to eyeball some of our measurements due to the constant motion of the springs, which could have slightly skewed our results. The general formula is v = 331 + 0.6 T at 20 C v = 343 m/s Some factors are: Temperature, humidity, air pressure. Hold the vibrating tuning fork so that the tines are horizontally aligned near the top of the tube, but not touching the tube. 6. I also learned that when a tuning fork vibrates at the same pitch as the air column, the sounds will come together and make a louder sound.
