1) frequency: The total number of cycles completed in one second is called frequency. Its unit is cycles per second or Hertz (Hz). Its formula is f = 1/ T, where T is time period.


2) cycle: The set of repetition of positive and negative instantaneous values of alternating quantity is called as cycle.

3) time period: The time required to complete one cycle is called time period. It is denoted by T. Its formula is T= 1/f, where f is frequency. And its unit is second per cycle.

4) amplitude: the maximum instantaneous value of sine wave is called as amplitude.
