THERMAL RADIATION Meaning and
Definition
-
Thermal radiation refers to the electromagnetic radiation emitted from an object as a result of its temperature. It is a form of energy transfer that occurs due to the movement of charged particles within an object. This radiation is typically in the form of infrared radiation but can also include visible light and radio waves, depending on the temperature of the object.
The emission of thermal radiation is governed by Planck's law, which states that the intensity and wavelength distribution of the radiation is determined by the object's temperature. As an object increases in temperature, the amount and frequency of the emitted radiation also increases. As a result, hotter objects emit higher-energy radiation, while cooler objects emit lower-energy radiation.
Thermal radiation plays a crucial role in various physical processes, including heating, cooling, and energy transfer. It is the main mechanism through which heat is transferred by radiation, allowing warmth from the Sun to reach the Earth and enabling objects to become warm when placed near a heat source. Additionally, thermal radiation is used in several applications, including thermal imaging technology, where it is utilized to detect and analyze the distribution of heat in objects and surroundings.
In summary, thermal radiation is the electromagnetic radiation emitted by an object due to its temperature. It is a fundamental mechanism of heat transfer and plays a significant role in various scientific and practical applications.

Etymology of THERMAL RADIATION
The word "thermal" is derived from the Greek word θερμός (thermos), meaning "hot" or "warm". The word "radiation" is derived from the Latin word radiatio, which means "a shining" or "radiance". Combining both terms, "thermal radiation" refers to the emission of electromagnetic radiation caused by the heating of an object or substance.
