What term describes the transfer of heat through electromagnetic waves?

The term that describes the transfer of heat through electromagnetic waves is radiation. This process does not require a medium to transfer heat, meaning that heat can move through the vacuum of space, which is particularly relevant in contexts such as sunlight reaching Earth. Radiation involves electromagnetic waves, allowing energy to be transported even across vast distances, unlike conduction and convection which do require a material medium (solids for conduction and liquids or gases for convection). Induction, while frequently associated with electromagnetic processes, specifically refers to the generation of electricity in the presence of a changing magnetic field, not heat transfer through waves.
