Answer:
98,280.8 Hz
Step-by-step explanation:
Here is the wavelength formula.
s = λ f
Note: λ is the wavelength, s is the speed of sound, and f is the frequency.
We are given the speed of sound and the wavelength. Using those 2 values we can solve for the frequency.
But first we have to convert mm to m.

![x=0.00349](https://img.qammunity.org/2023/formulas/physics/college/110moff5vhueftbyghnanai59l350le50l.png)
Now we have
![343=0.00349f](https://img.qammunity.org/2023/formulas/physics/college/ddpa9qlo7fbv2g6nb215e7uguqedwsx9n3.png)
Divide both sides by
