Answer:
Speed and wave length.
Explanation:
The frequency of a sound wave is also what we would call the pitch, a really fast and short wave lenght will create a high pitch, while a really slow and long wave length would create a low pitch in the sound wave. The formula for frequency is given by the next formula:
[tex]f=\frac{Velocity}{wave length}[/tex]
As you can see from the formula, it is velocity and wave length that determine the frequency of a soundwave.
