Fighting the Current

"What the hell?" you wonder....

Alright, I have asked two people what an oscilloscope is, just to see what their answers would be. Neither had a clue.

For those of you unacquainted with oscilloscopes, an oscilloscope is a device that is used to see radio/sound/etc waves. It looks like a little TV screen with a bright green line going horizontally across the middle. Depending on the frequency (I think that's the word I'm looking for...), the line moves in a wave motion. It's kinda hard to explain.... I'll see if I can find something to compare the image on it with. I know I've had to learn waves in science classes several times, maybe if you can think back to yours... (crest, trough, wavelength, etc. Jogging your memory yet? lol)
