String linear mass density (grey): h = 8.83 X 10-4 % Use this string for Parts A and B and one trial of Part C.
fn =n
n =1,2,3,
where L = string length; v = T /u , and T = mg T = tension in string H = linear mass density
Part A
Vthe
T /u
Vexp = 1f
m
Loops are fullest at a resonant frequency:
With string length constant, for each of six trials, increase the hanging mass thus increasing string tension T. For each trial, adjust the generator frequency to get the n = 2 (one wavelength) resonance.
Only for Part A, use graphing software to plot (vexp vS. T): Slope of best-fit line is 1/u _ Include in data table the best-fit calculated u from graphing software.
