wave behavior

Whether it is a stone tossed into a glassy-smooth pond, sound waves coming out of a trombone or electro-magnetic waves enabling radios to communicate, the wave behaviors are direct relatives to the physicist.

One such person built a model to demonstrate wave behavior then his employer, Bell Labs, produced a movie of it. I almost called it a video, but those were not yet invented in 1959 when this was produced.

Last year I pounded enough correct answers into my head that I passed my Amateur Extra exam. My motivation was that I really wanted to UNDERSTAND radio much better. I did not clear that hurdle on pure expanded knowledge of radio, but I found several tools that helped.

I wish I had repeatedly watched John Shive’s demonstration a long time ago. The visual images he created help me understand all the theoretical explanations and give me hope I may really grok this someday.
