Well...I am not sure this is what you need...but...
Frequency, f, is the number of oscillations in the unit of time (1 second) and is given as the reciprocal of the Period, T, (which is the time taken for one complete oscillation) so:
f=1/T measured in s^-1 called Hertz.
Frequency is also related to wavelength, lambda, as: c=lambda*f where c is the speed of light.
Also, frequency is related to Energy, E (of a photon), through the Einstein's relationship: E=h*f where h is Planck's Constant.
