Here's why:
* Heat and Radiation: All objects with a temperature above absolute zero (-273.15°C or -459.67°F) emit infrared radiation. This radiation is a form of heat energy.
* Electromagnetic Spectrum: Infrared radiation falls within the electromagnetic spectrum, which encompasses various types of radiation like visible light, ultraviolet, and radio waves.
* Invisible to Humans: While we can't see infrared radiation, we can feel its effects as heat. Night vision cameras and thermal imaging devices are used to detect and visualize infrared radiation.
So, while all objects emit infrared radiation, the amount of radiation depends on the object's temperature. Warmer objects emit more infrared radiation than colder objects.
