Does a photon have spatial dimensions.Also do two photons having different energy occupy the same volume?
Thnx
Thnx
I quote marlon from one of the threads in the Quantum Forums as he explains the crux of the matter so eloquently;I went thru a few of the topics u had suggested,but i fail to understand how a photon is a point particle.This is as energy occupies space and time so shudnt a photon:zzz:
Just to add. Keep in mind that a photon is defined as a quantum of energy. So it is designated by a number in an energy-coordinate space, NOT in a spatial coordinate space. So a photon is not defined as an entity with fixed spatial boundaries, designated by numbers in a spatial coordinate base.
Just as an addendum

The "size of a photon" has been discussed regularly here. You might like to review some previous threads:

Tip: concentrate on links that do not contain "archive" in the URL. The archive versions of threads don't have information about quoting, which can make reading them confusing, because it's hard to figure out who wrote what.
But still..Energy occupies space isn't it.I am sorry and thank all of you for being patient.But does energy occupy space or not(I think so as it also curves space-time)
Please be more polite .I am being straight-forward .Please be the same with me and please explain to me why a photon cannot have volume even though it occupies spacetime
Sure.What i understand is tht if something curves spacetime then it occupies spacetime.Now please tell me whether that is correct or not
Might be.And I am not saying if a photon curves spacetime it is spacetime(A=B)
.So please explain that y cannot it be that a photon occupies space-time

Also, duz a photon travel in a wave?

what is meant by e=mc^2.Just for my knowledge,does it signify that masss and energy are related and mass is a form of energy.
I apologise, as I always seem to be quoting other people in reply to your threads, but most of your questions have been answered pretty comprehensibly, in your own threads. I draw your attention to the thread you created entitled https://www.physicsforums.com/showpost.php?p=1203679&postcount=7". And in particular, the following posts;is mass a form of energy or not?
The important point to note from Chris' excellent post above; is that you are attempting to reconcile two theories, QFT and GR, which as yet have been found to be incompatible. The photon has no place (as yet) in GR and curved space time.Essential caveat: as you probably know, quantum theory has proven hard to reconcile with the curved spacetime models used in general relativity, so it is currently difficult to say very much with certainty about how photons and other particles might be treated in the yet unknown quantum theory of gravity.

mass can be considered to be another form of energy
One of my more amusing typos! :rofl: Damn this Google toolbarAll indecently by me? Hoot, how could you? I assure you that while I was typing that without wearing any pants, I was wearing a bright smile!
