Understanding Frequency and Period

* Frequency (f): The number of complete wave cycles that occur in one second. Measured in Hertz (Hz).

* Period (T): The time it takes for one complete wave cycle to occur. Measured in seconds (s).

The Relationship

Frequency and period are inversely proportional. This means:

* Higher frequency = shorter period

* Lower frequency = longer period

Calculation

The formula to relate frequency and period is:

* T = 1/f

Where:

* T = period

* f = frequency

Applying the Formula

In this case, the frequency (f) is 250 Hz. Let's plug it into the formula:

* T = 1 / 250 Hz

* T = 0.004 seconds

Answer

The period of the wave is 0.004 seconds or 4 milliseconds.
