Your classmate says that a harmonic series of frequencies includes the fundamental frequency and integral multiples of the fundamental frequency. Do you agree or disagree?

Solution 21E By the definition of harmonic series itself it is clear that, the different frequencies of it are integral multiples of the base frequency or the fundamental frequency. Here the base frequency is the lowest frequency that one harmonic series has. The harmonic series is an arithmetic series in terms of frequency. In short, the frequency is quantized here in the units of the fundamental frequency. CONCLUSION: Your classmate is right who was saying the statement, “harmonic series of frequencies includes the fundamental frequency and integral multiples of the fundamental frequency” .
