Answer:
344.8 Hz
Explanation:
The frequency of a wave is given by:
[tex]f=\frac{v}{\lambda}[/tex]
where
v is the speed of the wave
[tex]\lambda[/tex] is its wavelength
Here we have
v = 793 m/s
[tex]\lambda=2.3 m[/tex]
Substituting into the equation, we find
[tex]f=\frac{793 m/s}{2.3 m}=344.8 Hz[/tex]
