(7%) Problem 6: Using special techniques 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 oscilliscope, we find the violinist plays a note with frequency f-805 Hz in figure (a).

What is the fundamental frequency for our violin in Hz? ーム14% Part (e) In terms of the fundamental frequency f, what is the frequency of the note the violinist is playing in figure (c)? e a general expression for the frequency of any note the violinist can play in this manner, in terms of the fundamental frequency fi and the number of antinodes on the standing waveA ▲ 14% Part (g) what is the frequency, in hertz, of the note the violinist is playing in figure (d)?
