Understanding the Relationship
The relationship between wave velocity (v), wavelength (λ), and frequency (f) is:
* v = fλ
Solving for Frequency
1. Rearrange the equation: To find the frequency (f), we need to isolate it:
* f = v / λ
2. Plug in the values:
* v = 100 m/s
* λ = 20 m
3. Calculate:
* f = (100 m/s) / (20 m) = 5 Hz
Answer: The frequency of the wave is 5 Hertz (Hz).
