Standing Wave Lab
Purpose:
To find the velocity of standing waves by finding and changing its variables.
Theory:
Experimental Technique
Data
Analysis:
Conclusion:
Judging by the answers, it appears that the answers are quite accurate, though the data does become less accurate as the # of nodes decreases, especially for the last ones. For these last few ones, where the %-diff slowly crawled into the ~20% and maxed at a 46.1 %-diff, the reason to this would most likely be due to the finicky nature of the oscillator. A few other plausible reasons would be the following: permanent stretching of the string, inaccuracies for "perfect standing waves" and its +/ masses, and frictional interference. All around, this experiment was a success.
