molecules/atoms (and is related to square root of Temperature).

Faraday supposed that this apply to the electric waves. Of course there the

measure.

So, sound propagates very quickly in the ionosphere (it's got a fairly
high temperature), but because there's not a whole lot of atoms around,
the attenuation will be quite high (essentially infinite, I suspect)

No. Acoustic waves from the Sun (aurora) are et the Earth quite strong.

And that's totally different than propagating something by EM waves.

Electric waves propagate in metal and in space. In the both media the
electrons vibrate. "I suppose we may compare together the matter of the
aether and ordinary matter (as, for instance, the copper of the wire through
which the electricity is conducted), and consider them as alike in their

That makes you correct. One must carefully state what is meant by
temperature and what is meant by heat.

It would be easy after Schmidt's experiment in vacuum. There the hot cylider
in air bends the light rays and the shadow diameter is bigger than for the
cold cylinder.
The same experiment in vacuum tell us if speed of light is electrons
temperature dependent.

"acoustic waves" whatever you think they are do not propagate through a

But that is not how the waves propagate. In either material.

No. Acoustic waves from the Sun (aurora) are at the Earth quite strong.

"acoustic waves" whatever you think they are do not propagate through a
vacuum.

"The Earth is constantly immersed in the solar wind, a rarefied flow of hot
plasma (gas of free electrons and positive ions) emitted by the Sun in all
directions, a result of the two-million-degree heat of the Sun's outermost
layer, the corona. The solar wind usually reaches Earth with a velocity
around 400 km/s, density around 5 ions/cm3 and magnetic field intensity
around 2-5 nT (nanoteslas; Earth's surface field is typically 30,000-50,000
nT). These are typical values. During magnetic storms, in particular, flows
can be several times faster; the interplanetary magnetic field (IMF) may
also be much stronger."

The aurora is NOT caused by acoustic waves.

" In the explosive event that a coronal mass ejection (CME) is reported it's
time to hop into action because this super-charged solar wind is traveling
fast (maybe 3-to-5 million miles per hour). When this energy sweeps by the
earth 1-to-3 nights later there is a very good chance of aurora activity".

Do you think that ions and atoms in the solar wind do not vibrate?

How then?

Heaviside's statements are also old.

The topic is: " It was known that different frequencies travel with
different speeds on a
long cable".

Is the same in air and space?"

The answers were YES.

What do you want to add?

Sure... the number density of ionized particles is somewhat bigger than
the 5/cc you describe above, so solar wind is actually not a big
contributor to it. Most of the ionization comes from UV ionizing the
air atoms/molecules. (that's what the whole daytime sky wave off the F
layer is all about, after all.. working Australia from the California on
20 meters at 5AM CA time probably isn't a good bet)

That's not acoustic. That's just particles streaming out into space,
and because there's not many other particles to bump into, most of them
get to Earth

you produce hot wind also... you should learn to listen and get into
this century. no, the solar wind is not oscillatory, it flows from
the sun all the way past pluto. it also varies in speed quite a bit
so if the light was being propagated by the particles in the solar
wind we would see large changes in the velocity and intensity coming
from the sun that would be very easy to measure, and would likely have
killed off all life long ago.

no, the changes don't always make aurora, and they are definately NOT
small. watch the speed on this for a few months, even without aurora
and see how much it changes. if the waves were traveling on the

go to that link i gave you above, the 'normal' speed of the solar wind
like now is over 500km/s, it gets much faster when there is a coronal
hole or from a cme.
