$$T = \frac{1}{f}$$
Where:
- T is the period of the wave in seconds (s)
- f is the frequency of the wave in Hertz (Hz)
To measure the period of a wave, you can use the following steps:
1. Identify one point on the wave, such as the peak or trough.
2. Start timing using a stopwatch when the wave passes the identified point.
3. Stop timing when the wave passes the same point after one complete cycle or oscillation.
4. The elapsed time on the stopwatch is the period of the wave.
