Answer :
If the fundamental frequency which is 390Hz is multiplied, it will give frequencies of higher harmonics.
Fundamental frequency or the first harmonic is the lowest frequency at which a string could vibrate to form a standing wave pattern. If a violin string vibrates at 390Hz as it's fundamental frequency which is its first harmonic also called fundamental tone, then higher harmonics can be calculated by multiplying fundamental frequency.
Therefore,
- the first harmonic is 1×390= 390Hz
- second harmonic will be 2×390=780Hz.
- third harmonic will be 3×390= 1170Hz.
- fourth harmonic will be 4×390= 1560Hz.
Hence, these are the frequencies of the first four harmonics.
