While studying the type of signal propogation in telephone wires, I read that it has a bandwidth of 400-3000 Hz and the signal travels with the speed of light(as in case of all electric signals). So electronics at the two ends communicate atonce. One changes the voltage at one end and the other detects, it changes again and the other samples again. So the signal is transfered.
But if suppose we have a very long wire and the time of signal tranfer is finite(say 1s) and the electronics on one side change the signal before the voltage on the other side has actually changed. Does we have a so called voltage wave that travells?? What happens in that scenario?
