#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#
