Question

If a wave’s third harmonic has a frequency of 24 Hz, what is its
natural (fundamental) frequency and what is the frequency of H6?

Answer 1

the fundamental frequency is called the first harmonic
Higher harmonics are integer multiples of the fundamental
we know 24/3 = 8

1 f = 8
2 f = 16
3 f = 24
4 f = 32
5 f = 40
6 f = 48
