Two good videos that explain the difference.

An explanation of impedance matching and signal reflections in transmission lines using visual analogies and resistive divider concepts.
In this follow-up to my electricity waves video over on the main channel (youtube.com/@AlphaPhoenixChannel), I'm talking about impedance matching. This video is a bit more technical than the main channel video and I'd recommend brushing up on how resistive dividers work before we abstract resistive dividers into a soup of fake imaginary resistors in the second half of this video!

On “Can someone explain the concept of resistance in case of transmission cables ?”
A video I found useful: "Why doesn't a 75 Ohm cable measure 75 Ohms?", and also "What does "impedance matching" actually look like?"
