Hi,

I found a very useful "wave on a string" app at Phet (Coloardo University site). The app (it run in Flash) shows how waves are reflected back after hitting a fixed end. See http://phet.colorado.edu/sims/wave-on-a-string/wave-on-a-string_en.html

I am wondering if there is a similar app to illustrate electrical waves being reflected. What I would like to see, specifically, is how different terminating resistors effect the waves.

Thanks,

Dave

 

for electromagnetic waves, see "lecher lines"

 

Not an app but a nice video

Awesome, thanks all.
