Not 100% sure if this is supposed to be in Math or Physics...Admin please move if it is wrong...? 1. The problem statement, all variables and given/known data A long string under tension t having linear mass density u1 is tied to a second string with linear mass density u2 << u1. Transverse waves on the heavey string are incident on the junction. Find what happens to them. 2. Relevant equations I don't know :( 3. The attempt at a solution I do know tht when a wave goes through something with a different mass density, it changes the wave speed, but the frequency and amplitude stay the same, but that is all I really understand (and I am not even 100% on that). I think I may just be over thinking the problem, so any direction to start would be awesome. I know i have been asking a lot of questions, but I don't have a pre-req for this class, so I am trying to learn as I go...and sometimes and getting lost.
