A stroboscope was used to determine the frequency of the string
oscillator. Strobe frequencies fs were recorded
where a single stationary image of the oscillating string was
observed. The frequency of the oscillator f can be
determined from the stroboscope frequencies fs
by f = nfs where n is an
integer corresponding to the number of oscillations per flash. The
strobe frequencies produced were determined and tabled below:
m an integer, is determined to be 2.
The oscillator frequency is determined to be f = 45.65 Hz, from the average of nfs.
Use the mean error technique to determine the uncertainty f. Express the answer to two decimal places, with the SI unit included.
