See this old AT&T laboratory video ( http://techchannel.att.com/play-video.cfm/2011/3/7/AT&T-Archives-Similarities-of-Wave-Behavior ) for a magnificent explanation of how waves of any sort work, what happens to matched, partially-matched and un-matched impedance changes in the wave-guide.   Brief applications to radio waves, light waves, acoustic waves, mechanical waves, biological mechanisms, and simple machines.
Before you watch, can you name the 3-piece impedance matcher built into each person?
Follow up this introduction with a longer exploration, where Bill Hays presents the "Standing up for Standing Waves" lecture/demonstration using RF on a Lecher Line wave guide.
