British astronomer Sir William Herschel discovered infrared in 1800. Herschel knew sunlight could separate into components, which occurs when light refracts through a glass prism. He then measured the temperatures of the different colors created.

Infrared is commonly separated into near-, mid- and far-infrared. It can also divide into the following five categories:

Herschel found the temperature increased as the colors progressed from violet all the way to red light. Herschel then went a step further and measured the temperature in the portion beyond the red area. There, in the infrared area, he found the temperature was the highest of all.

In networking, wired and wireless operations use infrared light. Remote controls use near-infrared light, transmitted with LEDs, to send focused signals to home-entertainment devices, such as televisions. Fiber optic cables also use infrared light to transmit data.

Infrared light is invisible to the human eye, but heat sensors can detect longer infrared waves. Infrared shares some characteristics with visible light, however. Like visible light, infrared light can be focused, reflected and polarized.
