INFRARED RAYS Meaning and
Definition
-
Infrared rays, often referred to simply as infrared, are a form of electromagnetic radiation that falls within the non-visible spectrum of light. They have longer wavelengths than visible light, ranging from approximately 700 nanometers to 1 millimeter. Infrared radiation is generated by the thermal energy or heat emitted by an object. It is commonly associated with heat, as it is capable of transferring thermal energy without the need for physical contact.
Infrared rays are widely used in various fields due to their ability to penetrate certain materials and interact with the molecules within them. The radiation can be detected and measured with specialized devices such as infrared cameras or thermometers. Moreover, infrared is utilized in a range of applications, including scientific research, medical imaging, surveillance systems, and remote sensing.
Infrared radiation is divided into three categories: near-infrared, mid-infrared, and far-infrared. Near-infrared rays have shorter wavelengths and are often used in communication systems, such as remote controls. Mid-infrared rays are commonly employed in applications like night vision devices and heating systems. Far-infrared rays, on the other hand, have longer wavelengths and are frequently utilized for detecting heat signatures and imaging objects in thermal vision devices.
In conclusion, infrared rays refer to the non-visible electromagnetic radiation with longer wavelengths than visible light. They are generated by thermal energy emitted by objects and are widely used in various fields for purposes including detection, measurement, imaging, and communication.

Etymology of INFRARED RAYS
The word "infrared" is derived from two Latin terms. The prefix "infra" means "below" or "beneath", while "red" refers to the color red. This term was coined by the astronomer William Herschel in the early 19th century. Herschel observed that there were invisible rays beyond the red end of the visible spectrum of light which produced heat when directed onto a thermometer. He initially named them "calorific rays" but eventually changed the name to "infrared rays" to emphasize their position below the red light in the spectrum.
