Hello,

Does anyone has a copy of Lecroy Model 622 schematics and manual to share o=

Tappers,

I need a demo that shows a pattern moving at a speed that is slower than th=
e particles within the pattern.

For example, a pulse traveling in a slinky shows the opposite effect. Each=
coil of a slinky will individually move slowly while the wave pulse travel=
s quickly.

That is the opposite of what I am seeking. All the wave machines that I h=
ave, longitude wave machines, transverse wave machines, slinky, spring, and=
string all show the elements of the material moving slower than the wave p=
attern itself.

I need the opposite.

I am seeking to show a pattern that will move slow and the matter within th=
e pattern move fast.

One example I can think of which I cannot show in class is a water wave in =
the ocean. The water wave itself moves slow, while the water within the wa=
ve circulates about quickly.

Any ideas?

Thanks,
- Jerry

BTW for the curious this is to show an analogy for the Astronomical behavio=
r of the Spiral Density Wave of a galaxy and the motion of the stars within=
the spiral density wave.
