Charlie;
Scopes are neat as well as very handy.
\you should maybe Google oscilloscope and you will find a wealth of info on how they work and what they can do.
Be aware that to see a waveform, first of all you need an oscillating input source of some sort, as well as a trigger that fires the scope at some point on the waveform, usually somewhere on the leading edge on a +ve going voltage.
