The frequency \( f \) can be calculated using the formula:
\[
f = \frac{1}{T}
\]
where \( T \) is the period, which is the time between two crests. In this case, \( T = 5 \) seconds.
Now, substituting the value of \( T \):
\[
f = \frac{1}{5 \text{ s}} = 0.2 \text{ Hz}
\]
Therefore, the frequency is **0.2 Hz**.
