When we talk about standing wave patterns, the frequency is really important.
So, what is frequency?
Frequency is how many times a wave goes up and down in one second. We measure this in Hertz (Hz). This idea of frequency is closely linked to something called resonance, which we will explain more.
In standing waves, we have special points called nodes and antinodes.
Where these nodes and antinodes are depends on the frequency of the wave:
We can describe this relationship with a simple formula. The speed of a wave (v) is the product of its frequency (f) and wavelength (λ):
In standing waves, like those in strings or air in musical instruments, certain frequencies make specific standing wave patterns. These patterns follow something called the harmonic series, where each harmonic is a multiple of the main frequency.
Think about a guitar string. When you pluck it, you create a standing wave. The main frequency is the first harmonic, where there’s one antinode in the center and nodes at each end.
When you press down on the strings, you change the length that is free to vibrate. This changes the wavelength and frequency, which makes different notes. Each note you hear is a different standing wave pattern.
By understanding how frequency and standing wave patterns work, we can see how musical instruments produce sound. It also shows us how cool waves are in science!
