Physics, Astronomy & Cosmology / Re: Is there an experiment that shows the oscillation in the E field of light?

Colin2b, if you document the incident frequencies accurately one will not get new frequencies, ie addition and subtraction species unless there is a non linear element present to perform frequency mixing.
I understand what you are saying, but additional frequencies do occur in linear systems.
Alan & I regularly use beat frequencies to tune musical instruments. I agree that the individual component frequencies still exist, but it doesn’t change the fact that the beat frequency exists and has a physical effect, you can for example get it to excite a tuned resonator.
ES was very specific in his hypothetical example. If 2 optical waves did superpose to create a beat frequency, is it conceivable that if that frequency coincided with the absorption band of an atom then would an electron in that atom would absorb energy and make the transition.
The set up in ES’s description is difficult to achieve, but straight laser interference of 2 beams has been demonstrated in free space.
Look at a simpler demonstration in the paper below. Two beams are directed along the same path through a beam splitter and although the beat frequency is outside the optical band it’s effect is real and can be measured and monitored electronically. If the frequency happened to be at the right frequency is it not feasible that the atom might also act as a suitable detector.
I think that an atom is too narrow a filter to respond to the components, but in the spirit of ES’s question, if by some fluke the beat frequency were in the optical range would we see the beat as a colour, ES’s turquoise?

Unfortunately, none of this really helps answer ES’s basic question.

One can throw n+1 radio frequencies at a target and they will remain discrete ….
How do you know they remain discrete. Describe the detector that shows them to be discrete or non-discrete.
We are now firmly in the realm of rhe measurement problem.

Hi again,
   I'm sorry to write on the post again when no-one has had any time to respond yet.     

Now the question is:   Will the electron make a transition to the new orbital?   None of the individual photons from the lasers were of the right frequency for this to happen but will they combine under a superposition of their E and B fields to give you something that will be enough to make the electron jump? 

Best Wishes.
Hi ES
Sorry, still been away with unwell family member so not been following. So excuse if I’m covering something already discussed.

A photon is a measurement phenomenon which is detected when an electron in an atom is given sufficient energy to change state either by changing level or by being ejected (photoelectric effect). So the answer is yes, if the combined energies of the beams hit the sweet spot then the electron will transition and we say we have detected a photon. It’s all a bit circular and incestuous though and misunderstanding of what a photon is can cause a lot of problems, it’s why the phrase travels as a wave and interacts as a photon is often used.
In reality, getting this superposition right is very difficult as the lasers need to be very stable and fixed to large concrete blocks, but there have been some successful experiments on superposition - don’t have references to hand.

I like the idea @alancalverd  and thank you for your time.
   
    You do seem to be establishing that light carries energy.   I'm not sure if it tells me much about light being an oscillation in the E field.   If you fired lumps of blu-tack  (that's sticky clay stuff - but other brands are available)  at a cup of tea so that they just stick to the cup,  then you are transferring kinetic energy to the cup.   That's got to give you a warm cup of tea eventually.   I think that's how they do it at our local Cafe, it takes years and the cup is sticky.   I'm fairly sure they don't use oscillating E field blu-tack, just the regular stuff.
Worth having a deep think about Alan’s suggestion. Light doesn’t have mass, so that’s not the source of any energy transfer. When looking at electrons you would expect the charge to be affected by an electric field, which would transfer energy and is certainly the origin of the photoelectric effect. Unless you can think of a better transfer mechanism.
I did wonder about experiments using the optical Mossbaur effect with polarised light. There seem to be some experiments out there, but you would have to go through them to decide whether they answer your question.

Note, just got a warning of another post while I’ve been writing. Similar thoughts from Alan

I’m not aware of anyone who thinks space is empty.
It is, by definition.

Not to be confused with the universe, which consists of bits of stuff separated by space.
Space around me is filled with lots of stuff. The boss calls it clutter.

You are of course correct, I was trying to explain to Pasala on his own terms. Failed again  ;D

Quote from: pasala on 13/11/2022 16:05:30
I am also saying that space is not empty and it is completely filled with aether.  Basic question is how to find out this aether.  As per Classical view of light is that it is a disturbance in space.
The classical view is not that light is a disturbance in space.
As @Kryptid says, how do you define your aether, also how do you plan to detect it? There have been many attempts to detect an aether and all have failed. The main problem is that suggesting a medium in which light propagates usually results in light behaving in ways that experiment shows it doesn’t.

Quote from: Eternal Student on 13/11/2022 15:27:39
.Yes that's the right idea @evan_au .   Except that you need to take squares, so the probability of a photon passing the filter is 0.5 not 0.71...    Under classical field theory (so that is E and B fields) the intensity of light received is proportional to the square of the amplitude of the wave that is transmitted.   You resolve the incoming wave into components and get the fraction Cos 45°  for the amplitude that is transmitted exactly as you stated.  That means  Cos2 45°  =  ½  is the fraction in Intensity.   Then you can jump back to the particle and photon interpretation where  intensity  is just proportional to the number of photons received (per unit time and per unit area of the receiver).  Hence, you get the probability ½ for each photon.
Yes, you’ve hit on the main reason why a lot of people get confused with the polarisation experiments.

Sorry, I didn’t have time to reply properly before, just unpacking having returned from a 2 week trip to be alongside a relative in hospital. Not a lot of time available.

As you are aware, polarising plastics use long thin chains of molecules such that the electrons will oscillate along the chain and absorb the photons, whereas perpendicular to the chain there there is no absorption and the light passes through. The experiment you are looking for is a tricky one as you are trying to measure specific motion of electrons in the material and to do that means disturbing the very electrons you are looking to measure.
This experiment is takes a different approach and might be similar to what you are looking for https://www.sciencedaily.com/releases/2018/04/180410100941.htm

With regard to polarising filters I can't help wondering is there a rotation taking place?
You are still looking at this through classical eyes. The problem is that in subsequent measurements you are changing the bases (similar to coordinates) that you are using to take the measurements.

& Obviously Magic ain't Real.

P.S. - Just out of Curiosity, what about Placebo Effects?
It’s real, but it’s not magic.

Placebos won't lower your cholesterol or shrink a tumour, but they do work on symptoms affected by the brain eg perception of pain. They are most effective for conditions like pain management, stress-related insomnia, and side effects of cancer treatment, like fatigue and nausea.
Placebos involve chemicals the brain produces naturally eg feel-good neurotransmitters, like endorphins and dopamine, and greater activity in brain regions linked to moods, emotional reactions, and self-awareness.

"And I won't blame it solely on Russia, there are two sides to it". Yes, there are two sides to every dispute but that is no excuse to start the obscenity of war.
Like you I have been raised, or learnt, that there are two sides to every story. With that comes a distrust of those who say a problem is black or white, no grey. I also distrust marketeers, politicians, propagandists, and all those with a soundclip solution.

You need to read the whole essay Paul. It's about human behaviors. And a game of inequality.
No point, it’s a confused mismash of fact, some of which is now out of date,  and questionable opinion plus some swallowing of propaganda.

Quote from: yor_on on 23/10/2022 13:54:45
You can read this, a nuanced version, westernized. What Russia thinks about it should be obvious by now. Even for the most hard boiled 'patriots'.
It’s nothing to do with patriotism or flag waving. I feel no patriotism for Ukraine, just a deep sadness that a people who want to determine their own future, do away with soviet era corruption, and choose what sources of information they receive, and more, should be subjected to a most horrendous attack and mistreatment. That goes far, far beyond a reasonable response and it is hard to understand why anyone would want to defend that attack.
Interesting to note that terms like nuanced, westernised and hard boiled patriots, could come straight from a propaganda writer trying to put negative spin on an alternative viewpoint.

Doubt it. When schizophrenia is active, symptoms can include delusions, hallucinations, disorganized speech, trouble with thinking and lack of motivation. Don’t think a round table would be something they would do.
He is mentioned in a lot of early histories, although most are written at least 300yrs after his death.

Then you define it by its affects. You can't pull that definition back to mass/energy itself. In itself it is vague.
I don’t know what you mean by “Then you define it by its affects”. If you mean by its effects, then yes, that is science.
We observe and define everything by the effects they have.

Your ‘theory’ is wandering aimlessly all over the place. You have 48hrs to fulfil the requirement I outlined earlier “You have to show that your idea makes predictions that are correct, as determined by experiment, and which are not predicted by any other theory.”
Failure to do this means you will be considered to be trolling us and you will be removed from the forum.
