Sources Of Error In Resonance Tube Experiment
Show your calculations!Answer: The tube has a length of 0.350 m. DaveC426913, Jun 8, 2011 Jun 8, 2011 #6 Drakkith Staff: Mentor Sig digs = significant digits correct? What does this have to do with making music?This is how woodwinds work, the different finger positions cause the tube to become a different length, changing the wavelengths and frequencies. I used the speed of sound in air equation with the room temp at 28°C which was calculated at 348.6m/s. http://nzbsites.com/of-error/source-of-error-in-ohm-law-experiment.html

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 Answer Questions What is the correlation between the caliber of a gun and the amount of cows that are slaughtered for their milk-glands?
It has springs underneath and a person runs onto it. 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 Because the tubes are marked, we were able to record the different places at which resonance occurred. Tuning Fork Lab Sources Of Error I just want to know some source of error that may have caused this?
How much would that have changed the measured value of L?Because of the direct relationship between temperature and velocity, if one is increased, the other increases as well. Speed Of Sound Error Analysis It could also be due to rounding and calculation related issues. The graphs we compiled with the data we collected had R values that seemed to show how precise/accurate our data was - two with about .99 and one with about .98. The velocities were 76.5 and 69.1 m/s, respectively.
Expand» Details Details Existing questions More Tell us some more Upload in Progress Upload failed. Speed Of Sound Lab Conclusion The equation for length is L= n1/2(wavelength), the equation of a line is y=mx. Yes because its always the same (or fairly close to the same), indicating that its constant 2. This could likely be attributed to rounding errors when doing calculations.
- Lab: What is the relationship between a mass on a spring and its period of oscillation?
- View them here!
- Also, we did three trials of 5 periods to make our times even more accurate. 3.
- This was repeated at the "other end", and the results averaged, to cancel out any difference in microphone response time or propagation delay in the the signal paths from the microphones.Sources

Speed Of Sound Error Analysis
However, we believe the ones listed above are likely to dominate all other error sources. More questions Physics Speed of Sound 10 points!? Sources Of Error In Resonance Tube Experiment Redo graph #2 using the equation and explain these results. Resonance Lab Sources Of Error We did this until we found the 2nd and 3rd resonant length.
the relationship between frequency and harmonic number is linear. check over here Are your results any better when using the more accurate relationship (where m is the hanging mass and m2 is the mass of the spring)? The friendliest, high quality science and math community on the planet! 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. Resonance In Closed Air Columns Lab Sources Of Error

Calibration of the tuning fork- are you sure you are exciting with the frequency you think you are? What a resource! his comment is here The room temperature was higher than zero thus changing the results.
For the closed tube?open tube: The slope is equal to one half the wavelength. Standing Waves Lab Sources Of Error So for I have:- One possible source of error could be in the recording of data and in the plotting of the graph. The first graph (force vs.
Andy Resnick, Jun 9, 2011 (Want to reply to this thread?
The percent difference between these two was 9.9%. We repeated this several times, each time adding progressively more masses. 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 Speed Of Sound Resonance Tube Lab Conclusion And the relationship between frequency and wavelength is also power fit.
The microphones themselves are about 1/2 inch in diameter, and positioning them with a tape measure isn't very precise in any case. We can, therefore, disregard it.Oscilloscope time base inaccuracy. Please try the request again. http://nzbsites.com/of-error/sources-of-error-in-a-chemistry-lab.html The methods we used were conservation of energy and harmonic motion.
Data/Sample Calculations solving for mass per unit length: solving to find V (one way): solving for wavelength (first way) solving for wavelength (second way) Graphs/Analysis percent difference (velocity) percent difference (fundamental Each person has a different hearing level and therefore may perceive one sound as a maximum while another may determine a different one to be a maximum. The percent difference between the wavelengths we solved for was also very small - 6.73%. After I used the resonant length equation for a closed air column L=λ/4 (rearranged to find λ).
etc.. Summing the values given above, we find that the true speed of sound should fall within +4.2% to -7.2% of our measured value.The first two sources of error could be reduced Comments Sign in|Recent Site Activity|Report Abuse|Print Page|Powered By Google Sites Path:physicsinsights> misc > A Measurement of the Speed of Sound You can, of course, look up this value in lots of Objectives: To directly determine the spring constant k of a spring by measuring the elongation of the spring for specific applied forces.To indirectly determine the spring constant k from measurements of
When a tuning fork possesses the same natural frequency as the air column, thevibrations from the tuning fork will push the air particles at a frequency that will cause the air column Was part of your setup in relativisitic motion during the experiment?

This error could be avoided by taking care when reading data and recording it and also taking care when drawing the graph. Hi everyone, I am looking for 5 possible sources of error when carrying out a speed of sound experiment and give suggestions for a better result.
Factors can be introduced, and the corresponding speed change more easily understood. The frequency, used to calculate this, may not have always been 100% correct. A massless spring has a spring constant of k = 7.85 N/m. Please upload a file larger than 100x100 pixels We are experiencing some problems, please try again.
An application of this to real life situations would be in a gymnastics board. Place the PVC tube into the water. 4.
