if i remember correctly (after hopping around the room in agony trying to
remember this one), the formula is:
v = fw
v is velocity of sound in air at sea level at 20 degrees c in metres per
second (344m/s in this case)
f is frequency in hz
w (or an inverse y which i can't find on my keyboard, pronounced landa) is
wavelength in metres
to swap the formula around, w = v/f
or w = 344/120
so the wavelength at 120Hz is 286cm

does anyone want to back me up on this..?

cheers
