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?

• Science -

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
