(I) If a violin string vibrates at 440 Hz as its fundamental frequency, what are the frequencies of the first four harmonics?
What are harmonics? Harmonic of a wave with fundamental frequency f is a wave with frequency that is an integer multiple of the fundamental frequency f. I.e waves with frequencies 2f, 3f, 4f and so on are harmonics of the wave with fundamental frequency f.
The frequency of fundamental
So, the frequency of first harmonic
The frequency of 2"J harmonic
The frequency of 3"1 harmonic
The frequency of4,h harmonic
Thus, the first four harmonics are
