Question

For the following, enter your answers to at least three significant figure:s A group of students performed an experiment using the same setup as the one used in the Waves on Strings lab. The sample data is provided in the table below. Table 1 127 176 234 Copy this deta into GA and use it to make a frequency vs. number of antinodes graph. Determine the speed of the wave in the string. (Assune the distance between the end supports of the string is 0.23 m.) mys Take a screenshot of your graph and attach it as a file. Attach a rile that shows all the calculations. (Submit a file with a maximum size or 1 MB.) Choose Flc na fle selected If the linear density of the string equals 0.0020 kg/m and applied tension was 2.2 N, what is the theoretical wave speed? m/s

Explanation / Answer

For a string,
v = (lambda)f
and for number of antinodes, n
lambda = 2*L/n

so v = 2Lf/n
f/n = v/2L

From the Graph, f/n = 55.50

v = 2L*55.50 = 2*0.28*55.50 = 31.08 m/s

Theoretically
v = sqroot(T/mu) = sqroot( 2.2/0.0020) = 33.166
