Radiation

Definition

Energy emitted as electromagnetic waves across empty space, requiring no contact and no medium.

Radiation is one of the three ways to build a path for heat to move from hot to cold. It typically plays a negligible role in industrial water systems compared to conduction and convection. Because it needs no medium, it can cross a vacuum, unlike the contact dependent mechanisms.
