Understanding the Relationship
* Speed (v): The rate at which the wave travels (40 cm/s in this case).
* Wavelength (λ): The distance between two consecutive crests or troughs of the wave (8 cm in this case).
* Frequency (f): The number of waves passing a fixed point per second.
Formula
The relationship between these three is:
* v = fλ
Solving for Frequency
1. Rearrange the formula: f = v / λ
2. Plug in the values: f = 40 cm/s / 8 cm
3. Calculate: f = 5 Hz (Hertz)
Therefore, the frequency of the wave is 5 Hz.
