How Can I Determine Speed and Frequency with Only a Wavelength Component?

[StarGazer92]

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]

I can understand how this can be confusing. The formula for frequency (f) is equal to the speed of the wave (v) divided by the wavelength (λ). So in order to find the speed or frequency, you need to have both the wavelength and the other variable. If you only have one component, it is not possible to determine the other without additional information. As for the harmonics of your homemade instrument, the frequencies and wavelengths will depend on the length and shape of the air tunnel and the material of the instrument. There is no set speed for these frequencies or wavelengths, as they can vary depending on the specific design of your instrument. I would suggest doing some research on similar instruments or consulting with a music or physics expert for assistance in determining the harmonics needed for your project. Best of luck!
