reradiates

Emits absorbed energy

Reradiates means to radiate again or emit energy that was previously absorbed.

The term appears most often in physics and climate science: surfaces absorb solar radiation and then reradiate it as heat.

The earth's surface reradiates infrared energy back toward space.

The prefix re- emphasizes the secondary nature of the emission—energy passing through rather than originating from the object.
