it should have taken anyone around 10 sec search to find the beam is normally invisible, except for with the Science a GoGo forum and some of it's whacky inhabitants.
Bill S already knew that electrons are normally invisible
the reason I posted that electrons are invisible was for
your benefit ...
I believe that Bill S was asking WHY we could see the
light (the process)
and not whether or not the tube was designed so
that we could see the LIGHT.
several days go by after something is pointed out then you
jump in and start boasting about it as if you already knew it.
that's how you operate isn't it.
and then you say that you were waiting to see if someone
could figure it out first ... LOL
you remind me of Microsoft programmers who rely on
the user community to fix the problems in their operating systems then they incorporate those fixes into the OS as updates.
but you go one step further by laying claim on those fixes.
The light will spread randomly in all directions from the collision that absorbs the electron.
the light will spread in all directions , you can keep
your BS randomness.
how can light spread randomly in all directions.
collision that absorbs the electron. So you lose one electron and gain a photon emission from that point. It's very straight forward.
could you explain that process in detail?
1) what does the electron collide with?
2) why is an electron lost?
3) where does the lost electron go?
3) why is a photon gained?
its very straight forward so you should have no troubles
explaining the entire process involved from electron
collision all the way through to photon emission.
when you do it for kiddies do you explain the process
or do you just allow them to view the show?
