what is the difference between the two, if any?(adsbygoogle = window.adsbygoogle || []).push({});

In particular, I'm working on this transmission line problem where I'm given the time delay and the length. I can solve to find some sort of velocity--is it the phase velocity, or propagation velocity?

I also have the equation lambda = vp * T. Again, is this phase velocity or propagation velocity?

Thanks,

Sean
