Not 100% sure if this is supposed to be in Math or Physics...Admin please move if it is wrong...?

Homework Statement



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.


Homework Equations



I don't know :(



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.
 
Physics news on Phys.org
This is a 1-D wave scattering problem. You must apply two continuity conditions at the junction: continuity of displacement and continuity of positional derivative of displacement. Or, your book may have some formula that you simply plug into, which is a lot less work.

EDIT: sorry, I don't think that is the point of the problem question. Ignore the above.
