1. The problem statement, all variables and given/known data Consider the waveform shown below heading towards a boundary between two strings. Let string 1 have mass per unit length of µ1 = 0.05 kg/m and let string 2 have a mass per unit length µ2 = 0.02 kg/m. Let the tension in both strings be T = 100N. --> ____/\____ _ _ _ _ _ _ _ string 1 ... string 2 Using the reflection and transmission coefficients, sketch the reflected and transmitted pulses after the incident pulse has completely passed through the boundary. How do the width and height of the reflected and transmitted pulses compare to the incident pulse? 2. Relevant equations (Ar + Ai) * cos(wt) = At * cos(wt) Ai + Ar = At k(1) * (Ar - At) = -k(2) * Atr 3. The attempt at a solution r = (v(2) - v(1)) / (v(2) + v(1)) τ = 2*v(1) / (v(1) + v(2)) = 2 / (1 + v(1) / v(2)) v(2) = sqrt( (f * τ) / µ2 ) & vise versa v(1) / v(2) = sqrt( µ2 /µ1 ) r = (1-0.63)/(1+0.63) = 0.225, t= 1.225 I know the pulse in the lighter string should look like ___ _ /\ _ _ (taller but less wide) But how do I quantitatively illustrate that the width and height change, and by how much? Help is definitely appreciaTed!
