A guitar string has a linear mass density of 0.004 kg/m, a tension of 100 N, and is supposed to have a fundamental frequency of 110 Hz. When a tuning fork of that frequency is sounded while the string is plucked, a beat frequency of 4 Hz is heard. The peg holding the string is loosened, decreasing the tension, and the beat frequency increases. Before it was loosened and while it still had a tension of 100 N, The frequency...

Standing waves on a 1.5-meter long string that is fixed at both ends are seen at successive (that is, modes m and m + 1) frequencies of 38 Hz and 42 Hz respectively. The tension in the string is 720 N. What is the fundamental frequency of the standing wave? Hint: recall that every harmonic frequency of a standing wave is a multiple of the fundamental frequency. What is the speed of the wave in the string? What is the...

A guitar string has a linear mass density of 0.005 kg/m, a tension of 100 N, and is supposed to have a fundamental frequency of 110 Hz. When a tuning fork of that frequency is sounded while the string is plucked, a beat frequency of 2 Hz is heard. The peg holding the string is tightened, increasing the tension, and the beat frequency increases. Before it was tightened and while it still had a tension of 100 N, The frequency...

A rope with a linear mass density of 64 g/m is held under tension of 6 N. A student moves one end of the rope up and down, creating a wave on the rope. If the end of the rope is attached to a thicker rope, with a linear mass density of 182 g/m, what must the frequency of the wave be in the thicker rope? The student moves the thin rope up and down 6 times per second. The...
