This relationship is shown by the equation \(f= \frac {1}{T}\) Frequency is measured in Hertz, Hz. Period is measured using the 'timebase' (seconds per division) from the oscilloscope controls.

f = frequency = number of waves produced by a source per second, in hertz Hz. T = period = time it takes for one complete vibration or oscillation, in seconds s. A boat at sea bobs up and down as ...
