Formel
## 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.
Lösungsbeispiel
A guitar string: L = 0.65 m, T = 73 N, mu = 0.001 kg/m, fundamental.
- 01v = sqrt(T / mu) = sqrt(73 / 0.001) = sqrt(73000) = 270.2 m/s
- 02f = (1 / (2 * 0.65)) * 270.2
- 03f = 0.769 * 270.2
- 04f = 207.8 Hz
Häufig Gestellte Fragen
How does tightening a guitar string change the pitch?
Increasing tension increases the wave speed on the string, which raises the frequency and thus the pitch.
Why do thicker strings produce lower notes?
Thicker strings have greater linear density (mu), which reduces wave speed and lowers the frequency.
What are harmonics on a string?
Harmonics are integer multiples of the fundamental frequency. The second harmonic is twice the fundamental, the third is three times, and so on.
