A Piano that has a string of L = 2(m) long and a mass of m = 0.2(g) over that length. The Piano is tightened and its tension is T = 20(N). Determine the speed of propagation for a wave along that string? Let the fundamental mode has a wavelength of λ = L 2 Determine the frequency of sound associated with that string?

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...
