Answer:
λ = 338m
Explanation:
We can use the equation that describe the wavelength in function of the velocity and the frequency of the wave
λ = \(\frac{v}{f}\)
where v, is the velocity of the wave and f is the frequency of the wave
The problem gives you that \(v=23.0\frac{m}{s}\) and \(f=0.0680Hz\), so you should replace this values in the equation for the wavelengt:
λ = \(\frac{23.0\frac{m}{s}}{0.0680Hz}\)
λ = 338m
