This is a simple circuit showing two unmatched transmission lines. The first line is 75 ohms, the second line is 500 ohms. Waves traveling along the first line reflect at the boundary, causing a standing wave on the line, which is a wave that oscillates but does not move. It is actually a combination of two waves (the original wave and the reflected wave) traveling in opposite directions. The second line is properly terminated, so there are no reflections on it.
