INFRARED PHOTON Meaning and
Definition
-
An infrared photon is a fundamental unit of electromagnetic radiation, typically occurring in the infrared portion of the electromagnetic spectrum. It is a non-visible form of light that possesses energy and properties associated with its wavelength. As a photon, it behaves both as a particle and a wave, carrying discrete packets of energy.
Infrared photons have longer wavelengths than visible light, ranging from approximately 700 nanometers to 1 millimeter. They are emitted or absorbed by matter as a result of the movement or transition of electrons within atoms or molecules. This emission or absorption process causes changes in the energy levels of particles, producing the transfer of energy in the form of infrared photons.
Due to their longer wavelengths, infrared photons are capable of penetrating certain materials that visible light cannot, such as fog, smoke, or clothing. This property makes them useful in various applications, including thermal imaging, night vision devices, remote controls, and communication systems.
Infrared photons play a crucial role in many scientific and technological fields. They are utilized in medical applications to detect diseases, diagnose conditions, and conduct non-invasive tissue imaging. Additionally, they are employed in astronomy to study celestial objects and in climate science to analyze greenhouse gases. Furthermore, infrared photons are integral to the functioning of heat-seeking missiles and infrared cameras used in security and surveillance systems.
Overall, an infrared photon is a discrete unit of energy within the infrared spectrum that exhibits dual particle-wave behavior and finds numerous applications in many scientific, technological, and industrial domains.

Etymology of INFRARED PHOTON
The word "infrared" has its roots in Latin. "Infra" means "below" or "beneath", and "red" derives from the Latin word "ruber", meaning "red". Thus, "infrared" can be translated as "below red" or "beneath red".
The term "photon" comes from the Greek word "phōs", meaning "light". It was coined by the American physicist Gilbert N. Lewis in 1926 to describe the smallest indivisible unit of electromagnetic radiation, including visible light, ultraviolet light, X-rays, and so on.
So, when combined, the term "infrared photon" refers to the smallest indivisible unit of electromagnetic radiation that falls just below the red portion of the light spectrum.
