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………..)

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
