The discussion centers on the concept of electron recoil due to light emission, specifically addressing the Abraham-Lorentz force, also known as the radiation reaction force. It is established that when an electron accelerates and emits a photon, the conservation laws dictate that the electron experiences a recoil in the opposite direction of the emitted photon. The conversation emphasizes that classical physics models are insufficient for accurately describing this phenomenon, suggesting that Quantum Electrodynamics (QED) is necessary for a complete understanding.
PREREQUISITESPhysicists, students of advanced physics, and anyone interested in the interactions between charged particles and electromagnetic radiation.
Danyon said:Is the Abraham-Lorentz force (Also called radiation reaction force) the only recoil experienced by an accelerating charge? Say an electron is accelerating downwards, and that a photon emitted from this electron travels right, perpendicular to the direction of motion of the electron. Does the electron recoil to the left? or does it simply slow down in the direction of motion?
