Question

The frequency of the harmonics following a fairly simple pattern, as described in the text. If the frequency of the fundamental (n=1) harmonic is 70.0 Hz, what is the frequency of the second harmonic(n=2)?

    Answer:

    f2 = 140 Hz

    Explanation:

    let fundamental frequency is f1 = 70.0 Hz

    formula for finding the higher frequency when fundamental frequency is known

    fn = n f1          (where f1 is fundamental frequency and n = 1,2,3,4,5………..)

    for the second frequency n=2

    f2 = 2 × 70.0 Hz

    f2 = 140 Hz
