Here's a question I asked in the Introductory Physics forum that went unanswered. I'm trying it again in a different forum because I'm really curious about this.
Why do we say that electrons emit an electromagnetic wave when they accelerate but not when they travel at constant speed? In other words, what's different btw the "emited radiation" caused by acceleration, and the simple propagating deformation of the electric field caused by a moving charge?
