THERMAL RADIATIONS Meaning and
Definition
-
Thermal radiations refer to the electromagnetic waves emitted by any object or substance as a result of its temperature. They are a form of radiant energy that is associated with heat and are classified as infrared radiation.
When an object or substance is heated, its molecules become energized and start vibrating. These vibrations produce heat energy, causing the object to emit thermal radiations. The amount and intensity of thermal radiations emitted by an object are directly related to its temperature. The hotter an object is, the greater the energy of the thermal radiations it emits.
Thermal radiations are invisible to the human eye as they fall within the infrared region of the electromagnetic spectrum. However, specialized equipment such as thermal cameras or infrared sensors can detect and measure these radiations.
Thermal radiations play a crucial role in various fields, including physics, engineering, and medicine. In physics, they are a fundamental principle in the study of blackbody radiation and heat transfer. Engineering applications utilize thermal radiations for heating, cooling, and energy transfer. In medicine, thermal radiations are used in treatments such as thermotherapy, which involves targeting and selectively destroying abnormal tissues using focused heat.
Overall, thermal radiations encompass the electromagnetic waves emitted by objects or substances due to their temperature and are an important aspect of understanding and utilizing heat energy.

Etymology of THERMAL RADIATIONS
The etymology of the word "thermal" stems from the Greek word "thermos", meaning "hot" or "heat". It made its way into English through the Latin term "thermalis".
The word "radiation" comes from the Latin word "radiare", meaning "to radiate" or "to beam". This term is also related to the Latin noun "radius", which translates to "ray" or "beam".
When combined, "thermal radiations" refers to the emission of heat in the form of electromagnetic waves, typically in the infrared region of the spectrum.
