## Vibrating String

A string fixed at both ends supports standing waves whose frequencies depend on string length, tension, and mass per unit length.

### Formula

**f_n = (n / 2L) * sqrt(T / mu)**

where T is tension, mu is linear mass density (kg/m), L is string length, and n is the harmonic number.

Exemple Résolu

A guitar string: L = 0.65 m, T = 73 N, mu = 0.001 kg/m, fundamental.

  1. v = sqrt(T / mu) = sqrt(73 / 0.001) = sqrt(73000) = 270.2 m/s
  2. f = (1 / (2 * 0.65)) * 270.2
  3. f = 0.769 * 270.2
  4. f = 207.8 Hz
