In a stationary wave, how are harmonics related to the frequency of the wave?.
- A.Harmonics are multiples of the fundamental frequency
- B.Harmonics are half of the fundamental frequency
- C.Harmonics are independent of frequency
- D.Harmonics are always equal to the fundamental frequency
Model answer
What a good answer should say
- Harmonics are multiples of the fundamental frequency
Explanation
Why this works
Harmonics in a stationary wave are integer multiples of the fundamental frequency, which means the first harmonic is the fundamental frequency, the second harmonic is twice that frequency, and so on.
