A long cable is strung overhead in a
construction site. You occasionally note that the
vibrations due to heavy machinery set it vibrating.
You are curious about it so you time the vibrations. On one occasion you note that it vibrates at 0.6 Hz. On
another occasion it vibrates at 0.8 Hz. On a third occasion it vibrates at 1.0 Hz. You never observe it to vibrate
at any frequencies between these.
a) What is the most likely fundamental frequency (first harmonic) of this cable? [
b) Which harmonics are the ones that you have observed?
c) Sketch what the observed standing waves ought to look like.

Questions: 1. Explain how you can raise the pitch of a note on a guitar by altering the string’s (a) length, (b) tension, or (c) thickness or mass. Be very specific about what you would do to raise the pitch. 2. If the fundamental frequency of a guitar string is 250 Hz, what is the frequency of the second harmonic? Of the third harmonic? Explain. 3. Consider a vibrating guitar string. The loudest harmonic is the fundamental, but many higher...
Problem 2 [8 pts] Oscillator As a quality control technician at a violin string factory, you cut a sample of E-string off a large roll. The sample that you cut has a mass of ms = 1.021 grams and a full length of 2.5 meters. To test the string, you stretch some of it across a length L = 0.35 m, applying tension by means of a hanging mass m (as pictured). A variable frequency oscillator is used to excite...
12. A longitudinal standing wave can be created in a long, thin aluminum rod by stroking the rod with very dry fingers. This is often done as a physics demonstration, creating a high-pitched, very annoying whine. From a wave perspective, the standing wave is equivalent to a sound standing wave in an open-open tube. In particular, both ends of the rod are anti-nodes. What is the fundamental frequency of a 2.50 m -long aluminum rod? The speed of sound in...
