What are Infrared waves?

 

If you see the term IR, it means infrared radiation or infrared waves. IR is simply the abbreviation for infrared radiation. IR lies between microwaves and visible light. Infrared light cannot be seen, but it can be sensed in the form of heat. IR is used in the form of heat lamps for a variety of purposes, including keeping food warm in restaurants and for drying paint, wallpaper, and printing ink. Most remote controls use infrared signals to operate televisions. Then there are infrared imaging devices that are used by the military in locating enemy troops at night. Quite interesting!
