WebThe fundamental frequency is considered the first harmonic and the first partial. The numbering of the partials and harmonics is then usually the same; the second partial is the second harmonic, etc. But if there are inharmonic partials, the numbering no longer coincides. Overtones are numbered as they appear above the fundamental. WebDec 28, 2024 · The frequency at which this first standing wave, with two nodes and one antinode, is achieved is called the fundamental frequency or the first harmonic . The wavelength of the wave that produces the fundamental standing wave is λ = 2L , where L is the length of the string. Higher Harmonics for Standing Waves on a String
