Determining the Harmonic Frequencies

speed = frequency • wavelength
frequency = speed/wavelength
f2 = v / 2

speed = frequency • wavelength
frequency = speed/wavelength
f3 = v / 3

The frequency of the third harmonic is three times the frequency of the first harmonic. The frequency of the nth harmonic is n times the frequency of the first harmonic.

fn = n • f1

The inverse of this pattern exists for the wavelength values of the harmonics. The wavelength of the second harmonic is one-half (1/2) the wavelength of the first harmonic.

The wavelength of the third harmonic is one-third (1/3) the wavelength of the first harmonic.

And the wavelength of the nth harmonic is one-nth (1/n) the wavelength of the first harmonic.

n = (1/n) • 1
