Pictorial Veiw of Electromagnetism(Light)
If magnetism has never been observed in the Unipolar state, in which the state would/should be observed somewhat the same as an electric point charge, why do us humans pertain to draw LIGHT as a symetrical combination of both....when it is quite clear through simple observation that one exists in space completely differently to the other.
(For those that don't know.... Light in Physics books is drawn somewhat similarly to a DNA strand, with E and M feild/waves traveling perpendicular to each other as sine quantities..... Quantities...yes the drawings are somewhat only representing the quantative quality of light... but it really actually confuses most physics studuents into thinking that that is what light looks like (especially when text books illustrate it in the 3d representation.)
...so what should light look like... or more accuratley...what does the concert of E/M feilds sitting the in pathe of least resistance (space/time) look like.

Yes, that dual planar sine wave pix is the standard model It is ultimately a poor one and will remain due to a consequence of Von Neuman's Catastrophe of the Infinite Regress.. .
While light is a fine medium for both real world observation, and for use in our mental (philosophical) models, when the item under observation, or being considered are very differently scaled in mass energyM it cannot be used to observe or represent itself!
That is to say that we cannot look at light with light. Our models are incomplete. If we really try to complete them they will become self referential and useless.
So that model is god as it gets until we have a better observational method.

Light behaves as both a particle and a wave. It can be both drawn as particles and in waves, but they usually draw it in waves because it is easier to visualize and see its properties that way. And because they behave as waves, they also have wavelength, hence that is why they are graphed as a sine or cosine wave. It's important to remember that what you call light is just a very small part of the electromagnetic spectrum that can be detected by the human eye. Light is not an electric point charge, it is the result changing/dynamic electric and magnetic field, and since it is a wave it is transferring energy.

Light is not a medium, and it can be directly observed by itself. Just think of a flashlight through a fog, or a laser pointer.
Absatively. But we can see it (or imagine it) only in terms of itself. Thus the paradox arises.
Further, the wave/particle duality is unique to the region of the tiny (terms of mass energyL, and so physically unfamiliar to us in the macroscopic realm.
Tellya what though, a bicycle in motion gives a good example od just such duality.

I do not see how there is any paradox, for I did not define light in terms of itself, nor is it defined in that way at all. Light is electromagnetic radiation that can be detected by the human eye.
This phenomenon has been known for over 100 years and it is not unique in any frame of reference. It has been observed many times over. As for whether or not it can be perceived by us, to that I say "so what"?
Ahhh. But the initial question was about how we may visulize light; to which the nub of my gist is: "poorly."

Alternatively, it can be represented as a bunch of rays reflected from an object to the observer.
Whether you think it is a poor representation is irrelevant; that is how they are visualized for the sake of simplicity.

--If magnetism (yes as a field) always exists as a by-product of an electric field....then wouldn't light's most rudimentary form be E only?

--If magnetism (yes as a field) always exists as a by-product of an electric field....then wouldn't light's most rudimentary form be E only?
A magnetic field is formed by an electric current, in fact it only exists when there is an electric current. An electric field does not produce a magnetic field. E is not a rudimentary form for light, because light is the result of a changing/dynamic, or for a more accurate term, a disturbance in the electromagnetic field (that is, it involves both an electric field and a magnetic field).
Also, light is the result of photons transferring from a high energy state to a lower one (which causes a disturbance in the electromagnetic field, hence the wave/particle duality of light).

ain't it the electron? ...shell state, produces a photon in classical chemistry?
Don't you find that strange that a magnetic field is a perpendicular (in 3d space) by-product of E ?
if this is the case... then shouldn't you be able to create a light beam out of nothing more than the generation of a pattern (space/time) of E? ...hence create the M that cuases the concert of Light...
..and if EM is nothing more than the information in the Void of Spacetime then should you not be able to change space by simply generating the right
'pattern' of space.
eg. Gravity.... is nothing more than the pattern that matter creates in the void... thereby attracting other patterns.

A photon is an elementary particle that is responsible for the phenomenon of electromagnetism. To be honest, my knowledge on this subject is still limited, but there are various resources on the subject, including information on why the magnetic field is perpendicular to the electric field (it is not a by-product of E). Try looking at these articles for more information:

It's not really a pattern, but it does have a frequency and a wavelength. Electromagnetism does carry information about a particular body or sound in space, but it is not a pattern in, or of, space.
And gravity is not a pattern either, it is a force that every object exerts on each other. Gravity attracts all other objects to each other.
Trying to think beyond Newtonian concepts may help....
Einstein wasn't thinking on classical 'objectifiable' lines. It's what enabled him to think about 'What would happen if I were to ride a light beam'.
I am trying to highlight the same... would would happen if Light and space were the only atomic constructs of our reality.
PS... the photon is just a concept, just like the wave.... we don't actually see a round ball that turns into a beam and visa-versa... instead we 'feel' the force that light exerts on an object, therefore describing it as a Particle with weight. ...this is newtonian thought.

oh oh...were going to get into a debate here.
a photon (the concept) has mass... thats why it's a photon.
it's the wave which is massless, just like a sound wave , it's how we picture an ethereal transgression.
