The period is the reciprocal of the frequency.

                    T  =  1 / f .

'Hz' = 'Hertz' means 'per second' or ' /sec '.

       440 Hz  =  440/sec .

The period (reciprocal)  =  sec/440  =  0.0022727... repeating

                                                             =  2-3/11 milliseconds
