Does a charged particle need to experience a momentum changing force to emit light? Or is it sufficient for an observer to accelerate relative to the particle?
Right.MackBlanch said:So, it's not relative motion that drives emission, but changes in a charged particle's momentum?
Right.MackBlanch said:For instance, if you shake one particle in a two particle system, the shaken particle will not experience an emission from the stationary particle?
mfb said:Inertial = no acceleration
Right.
Right.
An accelerated charged particle is a particle with an electric charge that is increasing or decreasing in speed.
Light is made up of photons, which are particles that have no electric charge. However, when an accelerated charged particle moves, it creates an electric field which can interact with other charged particles, including photons. This interaction is what allows us to see light.
Yes, light can travel without an accelerated charged particle. This is because light can also travel as a wave, and does not necessarily require a charged particle to propagate.
No, light does not require force to travel. As mentioned before, light can travel as a wave and does not need a medium or force to propagate. However, when light interacts with matter, it can exert a force on the particles it encounters.
An accelerated charged particle can affect the speed of light by creating an electromagnetic field. This field can cause light to either speed up or slow down, depending on the strength and direction of the field. In a vacuum, the speed of light remains constant, but in a medium, it can change due to the presence of charged particles.
