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:

Strobe Frequency fs
Hz
Oscillations per
flash n
23.2 m
15.3 m+1
12 m+2
9.1 m+3


Note that m is an integer, that you need to determine.
