Synchrotron radiation

Definition

Synchrotron radiation is the electromagnetic radiation emitted when charged particles, such as electrons, are accelerated in magnetic fields, typically at relativistic speeds. This phenomenon is significant as it generates a broad spectrum of radiation that includes infrared, visible light, and X-rays, making it essential for various astrophysical processes and studies.
