What Is Radiation Reaction?

Radiation reaction is a fascinating phenomenon that occurs when charged particles, such as electrons or protons, interact with electromagnetic fields. This interaction can lead to the emission of radiation, which is energy that travels through space in the form of waves or particles. The concept of radiation reaction is crucial in various fields, including physics, medicine, and engineering.

In simple terms, when a charged particle accelerates, it emits radiation. This emission can affect the particle’s motion, leading to what is known as a radiation reaction. This reaction can be understood as a force that opposes the acceleration of the charged particle, effectively altering its trajectory and energy. The study of radiation reactions is essential for understanding phenomena in electrodynamics, astrophysics, and even in medical applications like radiation therapy.
