137200Hz

Explanation:

According to the following equation

v=λf

The frequency will be

f=v/λ

Where:-
f is the frequency (in Hz or s^-1)
v is the speed (in m//s)
λ is the wavelength (in m)

Assuming the temperature is 20^@C, the speed of sound at 20 celsius is 343 m//s, and assuming the wavelength is in meters, the frequency will be:-

f=343/0.0025

color(white)f=137200Hz
