Please let me know if any links don't work or have died. I run a linkchecker regularly, but some websites seem to get 'redecorated' constantly...

Formulas :
Frequency = 1 / the period of one cycle (Ex: 1 / 10 milliseconds = 100Hz)
FYI: Period of one cycle = 1 / Frequency (Ex: 1 / 100Hz = 0.010 seconds = 10 millisec's)
Wavelength (lambda, Λ) = Velocity / Frequency
Wavelength = The distance it takes for a wave to complete one cycle, in feet or meters.
Velocity = Speed of Sound (~1130 feet per second, ~1ft/msec, ~344 meters per second)
Frequency = Cycles per second (Hz)
