Are photons vibration or is vibration the transport medium for light? In what kind of medium are photons more transferrable?
I would not say vibration has anything to do with it. The word vibration brings a concept of a medium and there is no medium for light.itallcomestoenergy said:Are photons vibration or is vibration the transport medium for light?
ESL. In the visible spectrum (some hundreds nm) There are vibrations included, right? Where does this come in? Every mediums transport includes some form of vibration, is my form of perceptionHallsofIvy said:First, in regard to you title, "Photons bending": photons don't bend- their paths bend in a gravitational field. The medium for light is the electro-magnetic field that pervades the universe.
But photons need some kind of matter to travel thru. Is there a different kind of frequency for the different kind of matter the photons travel thru? Does blue and green operate in a different frequency in different mediums?Dale said:I would not say vibration has anything to do with it.

Your are not missing anything. My point is that there are some kind of transport-medium in space, right? It is not totally empty out there. What about gravitational waves, their energy travels thru something before they affect matterHallsofIvy said:Am I missing something here? The original post asked in what medium "light" is vibrations. I answered that light consist of vibrations in the electro-magnetic field. Now you are saying "But photons need some kind of matter to travel thru." NO! They don't! Where did you get that idea? Light, photons, from stars thousands of light years from Earth travel through empty space, not "through matter"!
Than what is it? Do we have a name for it? The electro-magnetic field is not every where in space? There are lots of light in space, but nothing to attach it to. A paradox, right?HallsofIvy said:The "transport medium" for light, as I said before, is the electro-magnet field. That is definitely NOT "matter".

No, they don’t. They travel through vacuum just fine. This is well established by two facts. First, there are vacuum solutions to Maxwell’s equations. Second, there has never been a successful detection of a luminiferous aether despite many sophisticated tests to do so.itallcomestoenergy said:But photons need some kind of matter to travel thru
Ok, but in vacuum we can detect particles that appear an dissapear, right? Snd inthe vacuum of space there are also atoms, right?Dale said:No, they don’t. They travel through vacuum just fine.

No. You may have been misled by non-technical descriptions of "vacuum flucuations" and "virtual particles" - these are a (generally well-intentioned) best effort at a math-free explanation of concepts that cannot be properly explained without math, so are often seriously misleading.itallcomestoenergy said:Ok, but in vacuum we can detect particles that appear an dissapear, right?
In space there are comparatively very few atoms, that is low density, compared to e.g. the atmosphere of Earth. And those atoms are not arranged in any orderly fashion like a grid.itallcomestoenergy said:Snd inthe vacuum of space there are also atoms, right?
Yes, and there are very large (meters) gaps between them. Light can travel in the empty space between the atoms just fine. Light has no need for a material through which to propagate.itallcomestoenergy said:Snd inthe vacuum of space there are also atoms, right?
If there is no light in space, than how do we have light on this planet?davenn said:that is meaningless
what paradox ??
Do you know/understand that photons are not little particles of mass shooting through
space etc like bullets ?
There is light in space, but there is no material medium (e.g. ether) through which light propagates.itallcomestoenergy said:If there is no light in space, than how do we have light on this planet?

Okey, so the medium is vacuum. With hints of atoms(?) What about sound waves? They operate in a lower frequency, but they are not transferrible in vacuum? Do I get this right? The reason I ask is because of illustrations of lights frequency spectrum.DennisN said:There is light in space, but there is no material medium (e.g. ether) through which light propagates.
So gravity affects the receptive issue of photons. Then where does sound waves come in? I have this picture that everything is vibration. Vibration in the lower sector causes sound, and in the higher sector causes visable light. Am I far out? And if so, where can I find understandable information about this subject?Dale said:No, they don’t. They travel through vacuum just fine. This is well established by two facts. First, there are vacuum solutions to Maxwell’s equations. Second, there has never been a successful detection of a luminiferous aether despite many sophisticated tests to do so.
This I don't get, and pardon my knowledge. Is it like if you are very far away from a light source (stars) there is total blackness?DennisN said:There is light in space, but there is no material medium (e.g. ether) through which light propagates.
Can you send me a basic understandable insight article?Nugatory said:No. You may have been misled by non-technical descriptions of "vacuum flucuations" and "virtual particles" - these are a (generally well-intentioned) best effort at a math-free explanation of concepts that cannot be properly explained without math, so are often seriously misleading.
We have a number of Insights articles on this subject, and there's really no substitute for a serious quantum field theory textbook... but the quick summary is: Vacuum really is vacuum with nothing there, and that doesn't stop electromagnetic and gravitational fields from propagating through it.
Not sure what you’d consider “understandable”, but this one might be a good start: https://www.physicsforums.com/insights/vacuum-fluctuation-myth/itallcomestoenergy said:Can you send me a basic understandable insight article?
That is not right. Sound waves are oscillations in the air pressure and electromagnetic radiation is oscillation in the electromagnetic field. They are no more related to one another than either one of them is related to water waves, which are oscillations in the depth of the water.itallcomestoenergy said:I have this picture that everything is vibration.

No. We have no trouble seeing the light from stars that are hundreds of trillions of kilometers away from us.itallcomestoenergy said:This I don't get, and pardon my knowledge. Is it like if you are very far away from a light source (stars) there is total blackness?
This is wrong. You need to get rid of this picture.itallcomestoenergy said:I have this picture that everything is vibration. Vibration in the lower sector causes sound, and in the higher sector causes visable light. Am I far out?
So there is light and photons operating in every inch of our universe?Nugatory said:No. We have no trouble seeing the light from stars that are hundreds of trillions of kilometers away from us.
Thank you. And this 'thanks', I really mean and appreciate!Dale said:This is wrong. You need to get rid of this picture.
If this were correct then we would not get much light if any from the sun.
But they both are operating in the frequency-matter-world? Hz.Nugatory said:That is not right. Sound waves are oscillations in the air pressure and electromagnetic radiation is oscillation in the electromagnetic field. They are no more related to one another than either one of them is related to water waves, which are oscillations in the depth of the water.
Even if they have the same frequency, they are completely different phenomena. A 20 kHz sound wave is a very high-pitched sound, a 20 kHz electromagnetic wave might be used for radio communication with submerged submarines
Yes. Even areas that are completely dark to our eyes (such as the inside of deep caverns) are brightly lit in the infrared and longer wavelengths.itallcomestoenergy said:So there is light and photons operating in every inch of our universe?

“Hz” is just a convenient way of saying “per second”, telling us nothing about what is happening that many times per second.itallcomestoenergy said:But they both are operating in the frequency-matter-world? Hz.
