Rich, I'm not on your newsgroup. I'm posting from another group on the list
so you haven't seen me before. I'll note that radium is a well known poster
on the newsgroup lists as being an idiot when it comes to any scientific
matters.
That he's even considering that electricity has "color" shows how
little real knowledge about reality.
I never said electricity has color. I did say that AC current
electricity can generate monochromatic light if its frequency of
oscillation is in the visible-light range. If an electric current
changes direction 580 trillion times per second, it will generation
electromagnetic waves that vibrate 580 trillion times per second.
Electromagnetic radiation whose frequency is 580 THz will look green to
the average human eye.
I even stated that we canNOT see electrons, we only see photons.
If I were you, i'd not try to defend
him in any way or you'll end up in the same bucket of fools that he exists
in.
Here are some things I have said to show that I know that electricity
has NO color what so ever:
"Light is electromagnetic radiation, yes. However, light is not
electricity. Electricity and electromagnetic radiation are two totally
different things."
"The human eye cannot see electric current. It can see electromagnetic
radiation at the "visible light" range of frequencies. However,
electric current -- at any frequency -- is always invisible to the
human eye."
"Think of a sound analogy. We can hear mechanical vibrations between
20-20K hz approx. However, we cannot hear electric current at any
frequency, can we."
"Just like that, we can see electromagnetic radiation in the "visibile
light" frequencies but we cannot see their electrical equivalent."
"Electricity by itself is totally invisible and inaudible."
"We cannot see electric current even if it oscillates at a frequency in
the "visible light" range. "
"If an electric current oscillates at a frequency in the "visible
light" spectrum, then we can see photons emitted as a result of the
oscillating electric current but we can't see the electric current
itself."
"By "blue" electricity, I assume you are talking about the bluish-white
light that is generated when electricity is at a high-enough voltage to
pass through air. As the current passes through the air, the air heats
up to temperatures adequate enough to produce a bluish-white light.
This light, however, is incandescent, and nothing to do with the
production of light I am referring to. When I was talking about
electrically-generating 510 nm light, my description was to use an AC
generator that outputs extremely high frequency AC current that gives
of electromagnetic waves at 510 nm. As other posters have pointed out,
the electric current would have to change direction [alternate] at
around 580 trillion times a second. AC current almost always produces
electromagnetic radiation at the same frequency"
So yes, I am well aware the electricity has no color at all.
