Chalk Talk Infrared

The video tutorial explores the electromagnetic spectrum, focusing on infrared light, which is invisible to the human eye but detectable in other ways. It divides infrared into near, mid, and far categories, explaining their characteristics and uses. Far infrared, also known as thermal infrared, is associated with heat and is used in thermal imaging and weather observation. Near and mid infrared are used in electronic devices like remote controls. The video also highlights that all animals, including humans, emit infrared light, and some animals use it for sensing. Infrared provides valuable information about our environment and the universe.
