Dmitri Ramzaitsev 30.11.03 11B Physics Laboratory - "Waves in Strings" Data Collection The Harmonic Number 2 3 4 5 The Number of Nodes 1 2 3 4 Mass Pulling the String (in Kg) 0.3 0.1 0.030 0.015 This data does not include any uncertainties purposely. While the experiment was carried out, I noticed that the number of harmonics was not so clear every time. The mass at the end of the string could be change to ± 0.015 kg and we could not see any difference in the number of nodes. The additional mass simply displaced the nodes a little, but created none. Therefore, it is safe to say that there was no specific or accurate mass that we measured to create each harmonic. And because the masses that we used were accurate to the nearest gram, it is not necessary to include ± 0.0005 kg of and uncertainty since it does not make the experiment any better.
