How do the forces involved in EMR continue to occilate past emmision of a photon
If electric fields are created by an accelerated charged particle, such as an electron, and magnetic fields are generated by electric fields in motion, what are the individual fields that make up ...

Virtual photons and slowing down longitudinal wave propagation
It is often described, that virtual photons are mere mathematical constructs, that can turn to real photons if there is enough time and space. And also, that virtual photons can mediate longitudinal ...

How is electric field arising from photons? [duplicate]
This question has nothing in common with the question it is proposed to be duplicate e.g about virtual photons. The question is about a real radiation field where is known that no virtual photons ...

What produces the electromagnetic fields in the light wave when photons are chargeless?
If there’s an electromagnetic field in the propagating light wave there must be an electric charge producing it, but photons are charge less, so how are these electric and magnetic fields produced and ...

At what point in space do we measure the electric field of an electromagnetic wave?
In an electromagnetic wave, the electric field varies in magnitude and direction. This electric field is at some point in space, point in the direction perpendicular to its velocity. See the image ...

Where do photon gets its electric field without carrying charge?
Electric field is determined by the electric force per unit charge, but photon clearly doesn't carry charge so where do the electric field came from?

Which photons drive the Electromagnetic Wave?
When an EM wave is created, the source emits Photons with Energy X.
Are these photons the only traveling particles driving the energy (Electron Excitation) in the EM field? -- OR -- the photons ...

How in detail the rotation of the electric field component of light during transition through a polarizer takes place?
I ask "After a slit, are photons polarized?" and later found two answers for the question "Why does the electric field dominate in light?". From this two answers I have concluded or summarized, that ...

Why does a real/virtual photon interact only with charged particle?
A photon is the force carrier of an electromagnetic wave and it consists of an electric and a magnetic field propagating through space at the speed of light in vacuum.
It exhibits wave-particle ...

Difference between electromagnetic radiation (EMR) and Electromagnetic Field?
I'm a freshly graduated electrical engineer. One course that I really struggled with was Field Theory, because it was a lovely assortment of vector calculus and things that were explained to me well ...
