No, infrared light does not burn for eternity. Infrared light is a form of electromagnetic radiation, just like visible light, ultraviolet light, and other forms of light. It is characterized by longer wavelengths and lower energy compared to visible light.
Light, including infrared light, is produced by various processes such as thermal radiation, fluorescence, or emission from excited atoms or molecules. These processes involve the absorption and re-emission of energy by particles or the release of energy during chemical reactions.
However, light does not continue to exist indefinitely. It travels through space until it interacts with a material or is absorbed by an object. When light is absorbed, its energy is typically converted into heat or other forms of energy, depending on the nature of the material it interacts with.
In the case of infrared light, it is often associated with thermal radiation emitted by objects due to their temperature. When an object is heated, it emits infrared radiation, which carries away some of the object's thermal energy. This energy loss causes the object to cool down gradually.
So, while infrared light can persist for a certain distance before being absorbed or interacting with matter, it does not burn indefinitely. Its energy is eventually converted or dissipated into other forms.
