A constrained string with a length of 8.5 meters is vibrating at its fundamental frequency of 113.1 Hz. What is the frequency of the 7th harmonic on this string?
The fundamental (first harmonic) wavelength is 17.0 meters.
Second harmonic: 8.5 m
Third harmonic: 5.67 m
Sixth harmonic: 2.83 m
Seventh harmonic: 2.429 m
Frequency*wavelength = constant
= 1923 m/s
Seventh harmonic frequency = 792 Hz
