Thermal radiation is a form of energy emitted by a hot object in the form of electromagnetic waves. This energy can be described using a variety of synonyms. One such synonym is infrared radiation, which refers specifically to the electromagnetic waves within the infrared region of the spectrum. Another synonymous term is heat radiation, as thermal radiation is a common avenue for heat transfer. Thermal energy emission and radiated heat are also interchangeable terms that describe this process. Regardless of the specific term used, thermal radiation is an essential phenomenon in understanding the behavior of hot objects and their interactions with the surrounding environment.
