Question
Laboratory Manual for Physics 2750 2017-18 Why is it more accurate to calculate the wavelength by measuring the distance between the nodes that are the farthest apart instead of two adjacent nodes? 4. List a few reasons to explain why it was best to start with two antinodes in the standing wave pattern instead of one? S. 6. Approximately what mass m must one use to observe only one antinode in the standing wave patterni? The string will slightly stretch when additional mass is added to the mass hanger. What effect does the stretching of the string have on the results? 7.Explanation / Answer
4)
It is better because the end nodes are fixed/ends of the string. Any small errors in amplitutde can be transmitted through the string and can cause errors in measuring the accurate points of the nodes which are adjacent to each other. Between the two end nodes, the number of nodes through the string can be measured, the number in itself won't vary and the length of the string is already known. The wavelength thus can be calculated more accurately.
