Answer:
Suppose that the frequency of the first harmonic is F, then the frequency of the second harmonic will be 2*F
The third one will be 3*F
and so on.
Then:
a) the first harmonic is 262 Hz,
Then the third harmonic will be 3*262Hz = 786 Hz
b) if F is the frequency of the first harmonic, and we want to find this.
We know that the fifth harmonic frequency is 1700Hz
Then:
5*F = 1700 Hz
F = (1700Hz)/5 = 340Hz
c) We want to find the fifth harmonic such that we know that the third overtone frequency is 984 Hz.
An overtone is any frequency larger than the fundamental frequency; overtone is just another name for harmonic.
Such that the second overtone is the same as the second harmonic, the third overtone is the same as the third harmonic, etc.
Then the third overtone is the same as the third harmonic.
This means that if F is the first harmonic, then:
3*F = 984 Hz
F = 984Hz/3 = 328 Hz
And the fifth harmonic will be:
5*328 Hz = 1640 Hz
