If the fundamental frequency of a guitar string is 220 Hz,

Step 1 of 3

Frequency of  harmonics of a vibrating string can be found by using the mathematical expression,

Where, L - Length of the string

 n - Order of harmonics

  - Wavelength of the nth harmonics

Rearranging this equation we get,

 ---------------- (1)  

We know that, wavelength of the string and frequency of the string is related by the equation,

  -------------------- (2)

Where, v - speed of sound

 f - frequency of the string

Rearranging this equation we get, ? -------------------------- (3)
