An infinite string (-∞ < x ≤ 0) of linear density ρL and under tension T is attached at x = 0 to a second infinite string (0 < x < ∞) under the same tension but of linear density 1.5ρL. If a wave of angular frequency ω and amplitude A is traveling in the +x direction on the first string, find the amplitude of the wave traveling on the second string.
