STANDING WAVES
Standing Waves
- appear to be ‘standing’ still in their left to right motion
- in constant position
Standing Waves can occur when a wave interferes with it’s reflected self

Harmonics
On a musical instrument, the strings are fixed at both ends

On a musical instrument, the strings are fixed at both ends
This means that there must be nodes at each end, and this limits the possible vibrations (or oscillations) of the string

So this violin...er, viola, uhm...wierd guitar....????
In each one of these standing waves, the wavelengths produce a frequency that are known as harmonics.
The first standing wave has what is known as the fundamental frequency f.
The second standing wave has the second harmonic 2f.
The third standing wave has the third harmonic 3f.
