In particle accelerators, particles emit electromagnetic (EM) waves due to acceleration. However, electrons in atomic orbitals do not radiate because their orbitals represent standing wave configurations, resulting in no net acceleration of charge. This distinction explains the difference in radiation behavior between accelerated particles and electrons in stable atomic states. The clarification resolves the initial confusion regarding radiation in these contexts. Understanding these principles is essential for comprehending the behavior of particles in both accelerators and atomic structures.
