प्रश्न

Distinguish between an overtone and harmonic. 

अंतर स्पष्ट करें

उत्तर

Sr. No. Harmonic Overtone
i. The first harmonic is the natural frequency of vibration.  The first overtone is the next higher frequency of vibration. 
ii.  Harmonics are simply integral multiples of the fundamental frequency.  Overtones are not necessarily integral multiples of the fundamental frequency. They are frequencies other than the fundamental frequency. 
iii.  All harmonics may or may not be present in vibration  All overtones are always present in the vibration.
