Frequency is the number of waves that pass a fixed point in
unit time ; also the number of cycles or vibrations undergone during one unit
of time by a body in periodic motion . A
body in periodic motion is said to have undergone one cycle or one vibration
after passing through a series of events or positions and returning to its

It is used in transmission of electric frequencies thus
enhance communication as vibration of the same frequencies of the same resonate together.
