SUMMARY

The discussion centers on the phenomenon of radiation emitted by a charged particle undergoing constant acceleration. It is established that while the radiation reaction force, which relies on higher derivatives of position, is zero, a charged particle still emits electromagnetic radiation during constant acceleration. This contradicts some interpretations of Feynman's statements regarding radiation under constant acceleration. The consensus is that an accelerated charge does indeed radiate, regardless of the constancy of the acceleration.

PREREQUISITES
  • Understanding of electromagnetic radiation principles
  • Familiarity with Feynman's lectures on electrodynamics
  • Knowledge of classical mechanics, specifically acceleration and forces
  • Basic grasp of the concept of radiation reaction force
NEXT STEPS
  • Research the implications of constant acceleration on electromagnetic radiation
  • Study Feynman's Lectures on Physics, particularly the sections on radiation
  • Explore the mathematical formulation of radiation reaction forces
  • Investigate experimental evidence supporting radiation from accelerated charges
USEFUL FOR

Physicists, students of electromagnetism, and anyone interested in the principles of radiation and acceleration in classical mechanics.

If the acceleration of the charge is constant, it radiates. However, the radiation reaction force, which depends only on the third and higher derivatives of x with respect to t, is 0. How is this explained? Didn't Feynman say that, in fact, in the case of constand acceleration, there's NO radiation? I have also read that it is an experimental fact that an accelerated charge radiates, even if the acceleration is constant. This question has been really bugging me for many months. I still haven't been able to find the answer. SO WHAT'S THE DEAL HERE??

I think you will find that a charged object undergoing constant acceleration will emit electromagnetic radiation. I don't remember Feynman saying otherwise :o) Which wouldn't matter anyway.
