Answer:
The frequencies of the first four harmonics are 248 Hz, 496 Hz, 744 Hz, and 992 Hz
Explanation:
Given;
fundamental frequency, f₀ = 248 Hz
Frequency of the nth harmonic = n x fundamental frequency
First harmonic, f₁ = 1 x f₀ = 248 Hz
Second harmonic;
2f₀ = 2 x 248 Hz = 496 Hz
Third harmonic
3f₀ = 3 x 248 Hz = 744 Hz
Fourth harmonic
4f₀ = 4 x 248 Hz = 992 Hz
Therefore, the frequencies of the first four harmonics are 248 Hz, 496 Hz, 744 Hz, and 992 Hz
