ADD: in short, it happens for "any" frequency. This is how a voltage signal propagates. However, for DC it happens once because you see "change" in voltage only once and that's it. As you increase the frequency, you'll end up seeing more voltage waves due to "change" in voltage. That's when "reflections" come into picture - happens due to discontinuity in impedance. |
