Experiment:
Review the standing waves in string and answer the below questions:
(1) Using λ= 2L/n-1 plot a graph of frequency of standing wave, f, versus the inverse of the wavelength, IA, for the first value of hanging mass. Draw a "best-fit" line through the points and determine the slope of the line. What is the physical significance of the slope? What is the y-intercept of your line? What is its physical significance? Repeat this process for the other values of hanging mass.
(2) Using the value ν=λ/T=λf and the value for the tension in the string, F=Mg, calculate the mass per unit length of the string you used. From the known values of the mass of the string and its length, calculate the actual mass per unit length. Do your two values agree? If not, why?
(3) If the nodes were not formed at the extreme ends of the strings in your experiment but
you had still measured the total length L to find the wavelength, say, in 3 segment mode, what error would have been introduced?
(4) In determining the mass per unit length of the string, you ignored the fact that the string
stretches when under tension. Explain, what effect would this have on the data?
(5) Include the critique for this experiment.
