- Frequency (f): The number of waves that pass a given point per second is called frequency.
- The unit of frequency is vibration per second or Hertz.
-
Time period (T): The time taken to complete one full oscillation or cycle by the Wave is called the time period.
-
The SI unit of the time period is second (s).
