WebDec 5, 2024 · Then, you go back to the equation and replace: x = A ⋅ cos ( ω ⋅ t + ϕ) ⇒ 1 m = A ⋅ cos ( ω ⋅ 2 s + ϕ) Check that both A and ω are already known. That's why I started with them. You must calculate A and ω first. Then you can do this replacement. The boundary condition is especially easy if it gives you the instant t = 0. WebAug 2, 2024 · Consider the transmission and reflection of waves from a mass, m, at x = 0 on a string with linear mass density ρ and tension T, stretched from x = − ∞ to x = ∞, shown in Figure 9.3. Before we calculate the coefficients for reflection and transmission, let us guess the result in two extreme limits.
