Frequency (f)= 1/Period (T)  

Where:

• Period (T) is the time taken for one complete cycle of a wave or oscillation, measured in seconds (s).

• Frequency (f) is the number of cycles or oscillations per second, measured in Hertz (Hz).

To calculate the period from a given frequency, simply divide 1 by the frequency value. Here's an example:

Example 1: Let's say the frequency is 50 Hz. Period (T) = 1 / 50 Hz Period (T) = 0.02 seconds (or 20 milliseconds)

Example 2: If the frequency is 1000 Hz: Period (T) = 1 / 1000 Hz Period (T) = 0.001 seconds (or 1 millisecond)

So, by dividing 1 by the frequency in Hertz, you can calculate the period in seconds.
