Two questions about multiple EM fields in the same space

[S Claus]

Multiple electromagnetic fields can fill the same space simultaneously
as long as they have a different vibrating frequency. An example of
this is the fields present in sunlight, which can be separated with
the help of a prism. This is different from material objects which
cannot simultaneously fill the same space (except perhaps in some
cases).

A couple of questions about this:
1. what is the minimum difference that must exist in the vibrating
frequencies in order for the fields to not conflict with each other?
2. why does the vibration frequency make a difference? What I mean is,
what aspect in the structure of the Universe causes two fields with
different frequencies to be able to co-exist in the same space?

Thanks in advance,

that depends on how you measure them.

If there was no difference only a single wave would be detectable.
the two become one via a process called wave superposition,

Tune your radio...."medium wave" if you live in USA,
(they still use WWI technology)
All those radio waves fill space without influencing each other.

It? 1 / oo?

Yep, one wave with infinite, continuous spectrum. At least I think that's
what superposition yields.

Define "conflict"? Sure it's harder to tune into one radio station if there
is another on the same frequency but it's not impossible. For example they
could have different polarisations.

2. why does the vibration frequency make a difference?

It doesn't.

ok...I must say, thanks all of you who have replied to this thread. I
surely learned something. I thought that the EM fields were able to
"co-exist" in the same space only if they had different frequencies.

I surely did not know much did I

If you drop a pebble in a pond it makes ripples.
If you drop two pebbles you get two sets of ripples and they
pass through each other, existing in the same space at the same
time.
http://sciencealive.wikispaces.com/file/view/ripples.jpg

If you are a little dragonfly travelling with the ripple then
the ripple has no frequency at all, you stay with the crest.
Thus frequency is relative, it is different for different flies
in relative motion.

In this respect it is similar to sound waves: You
can have a lot of different sounds at the same
time, and they just add together to give the
overall total sound.

But when sounds (or EM waves) of identical
frequency are added together, there is no way to
tell the originals apart anymore... you just have
a single sound/wave at the summed amplitude. You
can say that the originals are still "co-existing"
(as contributors to the total) or that they are
now gone and replaced by the total. The key point
is that you can't tell them apart anymore, like
you could if they had been different frequencies.

Bullshit. No one had digital AM transmitters during WW1, and we
don't use the term "medium wave" in the US. Harris' Broadcast Division
builds modular digital AM, FM and TV transmitters in the US, and ships
them to customers around the world. Their modular concept allows them
to continue to operate at reduced power when a tray is damaged, or has a
complete failure. Additional trays or racks can be added, if the
station's needs change and the transmitters can be maintained by station
staff, if they have to.

Please do try to keep up with the facts.

All those radio waves fill space without influencing each other.

The Universe has strange aspects, does it?

None. EM fields don't interact. Photons pass through each other
regardless of wavelength.

See above.

That didn't last long. Hey git - orthogonal standing waves of
identical frequencies.

A couple of questions about this:
1. what is the minimum difference that must exist in the vibrating
frequencies in order for the fields to not conflict with each other?

Zero. Direction counts.

2. why does the vibration frequency make a difference? What I mean is,
