To find the frequency of a wave, you can use the formula:
\[
\text{Frequency} (f) = \frac{\text{Speed} (v)}{\text{Wavelength} (\lambda)}
\]
Given:
- Speed (v) = 8 m/s
- Wavelength (\(\lambda\)) = 2.0 m
Substituting the values into the formula:
\[
f = \frac{8 \, \text{m/s}}{2.0 \, \text{m}} = 4 \, \text{Hz}
\]
Therefore, the frequency of the wave is **4 Hz**.
