Question

A 4.28 m deep well acts as a closed pipe. When wind blows across the top, what is the third harmonic (f3) that it creates?

Answer 1

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

$\lambda = \frac{4}{3} L = \frac{4}{3} . 4.28m = 5.706m$

Now , we will find the third harmonic frequency from the wave speed formula:

$v = f\lambda \\\\f = \frac{v}{\lambda} \\\\f = \frac{343\frac{m}{8} }{5.706m} \\\\f = 60.1 Hz$

Therefore , the third harmonic (f3) is 60.1 Hz
