The third harmonic frequency from the wave speed is 60.1 Hz.
<h3>What is wavelength?</h3>
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
Now , we will find the third harmonic frequency from the wave speed formula:
Therefore , the third harmonic (f3) is 60.1 Hz
