Problem 23: Using special téchniques called string harmonics (or "flageolet tones"), stringed instruments can produce the first few overtones of the harmonic series. While a violinist is playing some of these harmonics for us, we take a picture of the vibrating string (see figures). Using an oscilloscope, we find the violinist plays a note with frequency f= 780 Hz in figure (a). b. Otheexpertta.com How many nodes does the standing wave in figure (a) have?
