Simple Acoustic/music question

Can someone tell me (definitively) what the wavelength for Middle C at room temperature is, or give me a decent link? I thought I read somewhere that it was ~1.3m.

Middle C, being equal to 261.63 Hz @ 20°C works out to 4.319076558499 feet per cycle, or 1.31647746818 meters.

Use the following formula:

velocity=frequency x wavelength

or

1129ft/sec = 523.2cps x wavelength in feet.

by my math that gives a wavelength of 2.15 feet.

These figures assume a temp. of 68 degrees fahrenheit and dry air at sea level.

I don’t remember my metric conversions offhand, but hopefully you can take it from there.

(sorry about the english units–it’s all I know)

hmmm… conflicting simulposts!

Opus–which one of us picked the wrong C?

doh! wrong octave. That’s what I get for answering on no sleep. Go with Opus’s numbers! (humbly retreats…)

Wow I really stretched the hell out of this thread…
