Power of Frequency Explained

The frequency of a repeated event is its number of instances per unit of time. It differs from angular frequency, and it sometimes implies temporal frequency for clarification. One event occurs every second, or one hertz (Hz) when measuring frequency. The time elapsed between events is measured by the period, which is the inverse of the frequency. For instance, if the reading of a heartbeat is 120 times per minute (2 hertz), the period, T, the space between beats, is half a second, i.e., 60...
