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.
