'''Infrared''' ('''IR''') is a type of [[electromagnetic radiation]] that is invisible to the human eye but can be felt as heat. It is a form of [[light]] that has a longer wavelength than visible light, making it invisible to the naked eye. Infrared radiation is used in a variety of applications, including [[night vision]], [[thermal imaging]], and [[remote sensing]].

== Overview ==

Infrared radiation is a type of electromagnetic radiation, which also includes [[radio waves]], [[microwaves]], and [[visible light]]. The term "infrared" means "below red", referring to its position in the electromagnetic spectrum below the color red. Infrared radiation has wavelengths ranging from about 700 nanometers to 1 millimeter.

== Applications ==

Infrared radiation has a wide range of applications in various fields. Some of the most common uses of infrared include:

* '''[[Thermal imaging]]''': Infrared radiation is used in thermal imaging devices to detect heat emitted by objects or beings. This is useful in a variety of fields, including [[law enforcement]], [[military]], and [[wildlife observation]].

* '''[[Remote sensing]]''': Infrared radiation is used in remote sensing technologies to detect and measure objects from a distance. This is commonly used in [[weather forecasting]], [[geology]], and [[astronomy]].

* '''[[Night vision]]''': Infrared radiation is used in night vision devices to enable visibility in low-light conditions. This is commonly used in [[military operations]], [[surveillance]], and [[wildlife observation]].

== Health effects ==

Exposure to infrared radiation can have both beneficial and harmful effects on human health. On one hand, infrared radiation is used in [[physical therapy]] to provide deep heating to treat conditions such as [[muscle pain]] and [[arthritis]]. On the other hand, excessive exposure to infrared radiation can cause [[thermal burns]] and [[eye damage]].
