I need help with an odd concept in transmission line wave reflections. So what I'm reading is that when you have a transmission line, the voltage and current characteristics are repeated every λ/2, they change phase every λ/4, and the impedance is repeated every λ/2 as well. Apparently this idea means you can reflect specific impedances for matching, or that you can use the transmission line for tuning.
There are pictures that show the voltage and current 180° out of phase going through a transmission line, they peak every λ/4 and intersect every λ/4. I just don't understand how the impedance is repeated, or how you can use this idea for anything that was mentioned above. I'm pretty new to transmission line theory so maybe I'm missing something. Help is greatly appreciated
