The third harmonic frequency from the wave speed is 60.1 Hz.
What is wavelength?
Wavelength is the distance between identical points in the adjacent cycles of a waveform signal propagated in space or along a wire.
Let's first find the wavelength of the wave.
The length wavelength relationship
[tex]\lambda = \frac{4}{3} L = \frac{4}{3} . 4.28m = 5.706m[/tex]
Now , we will find the third harmonic frequency from the wave speed formula:
[tex]v = f\lambda \\\\f = \frac{v}{\lambda} \\\\f = \frac{343\frac{m}{8} }{5.706m} \\\\f = 60.1 Hz[/tex]
Therefore , the third harmonic (f3) is 60.1 Hz
