SUMMARY

The discussion centers on determining the finger placement for a violinist to play concert A (440Hz) on a violin string tuned to concert G (392Hz) with a length of 0.35m. The correct approach involves calculating the velocity of the wave using the formula v = frequency * wavelength. The wavelength for concert A must be accurately derived, and the finger placement is determined by the ratio of the frequencies, leading to a placement that is less than the total string length of 0.35m.

PREREQUISITES
  • Understanding of wave mechanics and frequency
  • Knowledge of violin string physics
  • Familiarity with the formula v = frequency * wavelength
  • Basic skills in solving algebraic equations
NEXT STEPS
  • Research the relationship between frequency and wavelength in string instruments
  • Learn about the physics of standing waves on strings
  • Explore the concept of harmonic frequencies in stringed instruments
  • Study the tuning methods for string instruments like the violin
USEFUL FOR

Musicians, music educators, and physics students interested in the acoustics of string instruments and the practical application of wave mechanics in music performance.

Homework Statement



A violin string has a length of 0.35m and is tuned to concert G (a frequency of 392Hz). Where must the violionist place her finger to play concert A, with a frequency of 440Hz?

Homework Equations





The Attempt at a Solution



I used v= frequency * wavelength and found the velocity, then found the wavelength for concert A and devided by 2. Is this the right method?

Depends on what you used for wavelength. If you used 2*0.35, then yes, it's correct.
 


So would the answer be 0.624m?

I wouldn't think so. The violin sting itself is only 0.35m, your answer is nearly double it's length!
