SUMMARY

The discussion centers on determining speed and frequency using only a wavelength component in the context of a homemade musical instrument project. The key equation presented is the wave equation, expressed as v = fλ, where v represents the speed of sound in air, f is the frequency, and λ is the wavelength. It is established that one can assume a constant speed of sound for all relevant frequencies when calculating harmonics. This foundational understanding is crucial for accurately designing the instrument.

PREREQUISITES
  • Understanding of the wave equation v = fλ
  • Knowledge of the speed of sound in air (approximately 343 m/s at 20°C)
  • Basic principles of harmonics in musical acoustics
  • Familiarity with the construction of wind instruments
NEXT STEPS
  • Research the speed of sound variations in different mediums
  • Explore harmonic series and their application in musical instrument design
  • Learn about the impact of temperature on sound speed
  • Investigate techniques for measuring frequency and wavelength in acoustics
USEFUL FOR

Musicians, acoustics engineers, hobbyists building musical instruments, and anyone interested in the physics of sound and harmonics.

I'm trying to find out if there is a way to figure out speed and frequency with only a wavelength component, but having no such luck...I'm currently working on a project involving making a homemade musical instrument (I've made a kind of recorder with a closed air tunnel and I've done that, but I'm actually trying to figure out the harmonics needed. Is there a set speed for these frequencies or wavelengths? This is really confusing...

f = vλ

HELP! PLEASE!

I think you can begin by assuming the same speed (the speed of sound in air -- look it up) for all frequencies of interest.

The wave equation should be: [itex]v = f \lambda[/itex]
