The different perception on a maximum would directly affect the lengths and could throw off our data. Log in or Sign up here!) Show Ignored Content Know someone interested in this topic?

I am trying to think of possible sources of error that may have been done during the experiment to prevent my getting my 'desired value' We'd need to know what methods Conclusion: Our hypotheses proved to be essentially correct. What is the period T of oscillation? 7.

Sources Of Error In Resonance Tube Experiment

I understand your setup, but an oscilloscope, sound pulse generator, and a transmitter/receiver setup on a ruler is another good way to calculate speed. For example, what is the effect of a 0.5 degree shift in temperature? We repeated this several times, each time adding progressively more masses. Get it on the web or iPad!

• 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.
• Therefore, the harmonic number would ultimately change.
• The times, as seen on the screen (labeled "Delta" in the screen shots) were 2.960 and 2.820 mS, respectively; averaging them we obtain 2.89 mSec.Our separation was 1.016 meters, which leads

• This was compensated for by running the experiment from both ends and averaging.
• Trending I'll try again.

At 23 degrees C. The assembly was held onto the table with a clamp the prevent moving. Was your calculation accurate enough for the teacher? Though the mathematical view to this lab is not such a deal.

The relationship between frequency and harmonic number on the graph was linear, also as we originally predicted. Speed Of Sound Lab Conclusion Calculate the tension T that would be required to produce the n = 1 standing wave for the red braided string. - 2. There could therefore have been inaccuracy of as much as +/- 1/2 inch in the center of each microphone, or +/- 1 inch total. However, this can only occur if frequency is constant.

Sources Of Error In Resonance Tube Experiment The distance between their centers was measured with a tape measure. Resonance In Closed Air Columns Lab Sources Of Error tension graph also proved close to what it should be - .58 as opposed to .5.

Atheists, do you think the conclusion of the 'Schrodinger's Cat' thought experiment violates the law of noncontradiction? 22 answers The Pendulum? 7 answers Why do sound waves travel at a speed Newer Than: Search this thread only Search this forum only Display results as threads More... Was part of your setup in relativisitic motion during the experiment? get redirected here We could go on, I'm sure.

You can only upload a photo (png, jpg, jpeg) or a video (3gp, 3gpp, mp4, mov, avi, mpg, mpeg, rm). Sources Of Error In Standing Waves Experiment We then recorded the period of the oscillation of the spring moving up and down five times. What is the effect of changing frequency on the number of nodes? - As the frequency increases, the string is vibrated more which increases the number of nodes because there are

In order to turn this experiment into a metrology exercise, you have to account for all kinds of effects, some of which have been mentioned but others include: Properties of the

We attached the other end of the string to a pulley and table clamp, which held a hanging mass. Therefore, velocity also affects the number of nodes since the velocity affects the frequency in the equation v=λf. Assuming the length of the string will remain the same, harmonic number impacts the number of nodes as a result of the equation L=n*(1/2)(λ). Speed Of Sound Lab Physics Answers A longer string will give you a longer wavelength and fewer nodes.

Record it in your data table.11. How would that have affected the data? - The string’s velocity would increase as the tension increased. In figure 3 and figure 4, we see shots taken in each direction. http://phabletkeyboards.com/sources-of/speed-of-sound-lab-tuning-fork-sources-of-error.php Our hypothesis was that as frequency increased, resonance would increase as well, with a linear relationship.

Use the thermometer to measure the room temperature and record.

In both cases we measured the time from the peak of the first "hump" in the wave form at the leading microphone, to the time at the peak of the first However, we believe the ones listed above are likely to dominate all other error sources. Though, of course, there were multiple sources of error in this lab. This error could be avoided by taking care when reading data and recording it and also taking care when drawing the graph.

I am trying to think of possible sources of error that may have been done during the experiment to prevent my getting my 'desired value' n3w ton, Jun 8, 2011 Hypothesis: Both of the spring constants that we find should be the same. If the velocities were changed, the number of nodes at frequencies would be changed as well. 4. The percent difference between these two was 9.9%.

As expressed in a graph, the frequency and the number of nodes have a linear, or direct, relationship. Yes because its always the same (or fairly close to the same), indicating that its constant 2. wavelength graph (where velocity was the slope) and the other by calculating it in a formula based on our experimental data.
