SUMMARY

The calculation of the overtone frequency and wavelength for a vibrating string involves understanding the fundamental frequency and the harmonic number. The relevant equations are L = λ/2 * n and v = f * λ, where L is the length of the string, λ is the wavelength, n is the harmonic number, and f is the frequency. To find the overtone frequency, use the formula f = n/2L, which incorporates the tension (T) and linear mass density (μ) of the string. This discussion clarifies the relationships between these variables and provides a clear method for calculating overtone frequencies.

PREREQUISITES
  • Understanding of wave mechanics and harmonic frequencies
  • Familiarity with the equations of motion for vibrating strings
  • Knowledge of tension (T) and linear mass density (μ) in strings
  • Basic algebra for manipulating equations
NEXT STEPS
  • Study the relationship between harmonic numbers and overtone frequencies
  • Learn about the physical properties of strings affecting tension and mass density
  • Explore the derivation of wave equations for vibrating strings
  • Investigate practical applications of overtone frequencies in musical instruments
USEFUL FOR

Physics students, music instrument makers, and engineers interested in acoustics and wave behavior in strings.

How to I calculate the overtone frequency and the wavelength when I'm given the values to calculate the fundamental frequency of a string?

I've got equations such as:

L=lambda/2 * n, v = f * lambda (Maybe I'm missing one?) I don't know how to use them in this event.

Any hints?

Do you know what the meaning of the variable n is in the expression relating L and \lambda?

Just been looking over it again. I believe it's the harmonic number. Do I get the wavelength by Lamda = L

And I get the frequency by f = n/2L Squareroot(T/mu)?

Some people might use the phrase "harmonic number", but there is another common word that starts with "o".

As for your answer, you have two equations involving L and v, and neither one mentions mu or T, so those don't need to appear in your answer.
