Why does an accelerating electron(or any other charged particle) radiate electromagnetic radiation?
gpt
Imagine you are very far away from a charged particle, and you can detect its electric field.

Then the particle starts accelerating. The electric field far away from the charged object is no longer the same. However, the information that the source of the field has changed can only propagate at light speed. So the electric field has this disturbance propagating outward at the speed of light, which is what we call electromagnetic radiation.
