Isotropic radiation

Isotropic radiation refers to the emission of energy, such as electromagnetic radiation or particles, uniformly in all directions from a source. In other words, an isotropic source emits radiation with the same intensity regardless of the observer's position or angle relative to the source. This concept is often used in various fields including physics, astronomy, and engineering. For example, in astrophysics, many stars can be approximated as isotropic radiators, emitting light and heat evenly into space.
