16.4: Wave Speed on a Stretched String

To see how the speed of a wave on a string depends on the tension and the linear density, consider a pulse sent down a taut string (Figure 16.4.1 16.4. 1 ). When the taut string is at rest at the equilibrium position, the tension in the string FT F T is constant. Consider a small element of the string with a mass equal to Δm = μΔx Δ m = μ ...
