Question

Part B. A particular species of spider spins a web with silk threads of density 1300 kg/m3 , diameter 3.0 µm, and tension of 1.0 mN.

1. A passing insect brushes a 12-cm-long strand of the web and excites the lowest-frequency standing wave. With what frequency will the strand vibrate?

2. Graph the resulting wave (vs. position) from part (1). p. 3/3

3. Now assume the insect excited the second-lowest-frequency standing wave in the same strand. Now what is the frequency at which it vibrates?

4. Graph the resulting wave (vs. position) from part (3).
