How many photons pass through us every second?
I just read this answer https://physics.stackexchange.com/a/229374, which says that, when a magnet rotates, photons are emitted with wavelength $λ=c/f$, where $f$ is the frequency of rotation. And ...

Radiation from accelerated charged in a co-accelerated reference frame
I was wondering if I sit on a accelerated charge particle I will not observe radiation since the particle is at rest according to me. But my friend observes it from outside and he will see radiation ...

Does a charged particle under constant acceleration produce electromagnetic waves? [duplicate]
A charged particle at rest does not emit any electromagnetic waves. It is generally said that an accelerated charged particle does produce electromagnetic waves. But according to Einstein's Principle ...

The electric field due to a moving charge is in radial direction as well. Why?
According to special relativity the information can transmit only at the speed of light. However,the electric field at a point due to a charge moving at constant velocity changes its direction the ...

Accelerated Electric Charges
We know that an accelerated electric charge produces electromagnetic radiation.
We also know that acceleration is relative to an observer.
Take electrically neutral observers A and B, who are ...

Does a charged particle orbiting Earth radiate?
I found this question, for which the answers I did not understand:
Does a charged particle accelerating in a gravitational field radiate?
So I want to dumb it down.
From my backyard, can I see ...

Radiation of accelerated Charge: Impact on macroscopic objects
Accelerated charge obeys an energy loss due to radiation. This is one reason why the classical picture of electrons orbiting the nucleus would result in a non-stable atom since the electrons would ...

Energy conservation of oscillating electric field interacting with charged particles
Consider a charged particle at rest in a vacuum. A traveling oscillating electric field reaches the particle, making it oscillate as well. The particle has gained kinetic energy with that interaction, ...

How can a free electron "oscillate" in the presence of em waves?
I have been told a many times that in a region with oscillating electric and magnetic field, a free electron if left will also oscillate. But I don't think its true. I actually asked this to my ...

How Maxwell's equations predict how sources are affected by the EM fields?
Sources in classical electrodynamics, described by Maxwell's equations, are inmutable entities, that feel external; and most of the times, work as a mathematical tool for describing particles which ...

Do any of the color bands in a rainbow contain an electrical charge relative to clouds that might explain a photo of lightning striking a rainbow?
Caveat: While I am not a physicist myself, I am extremely interested in physical phenomena. I am well versed in electrical theory, and I am aware of the attraction between the bottoms of clouds and ...

Hi, I have a little doubt, do electric charge create EM field or disturb or enhance it? [closed]
What i mean to ask is that, i learnt that EM waves are just disturbance in the already ever existing EM field, so when there is a charge in space, does it enhance the field in its required direction ...
