Infrared visiona What exactly is infrared visiona
The infrared light is invisible, but the photons can interact with the electrons of atoms and molecules. When the electrons give up excess energy, visible light can be produced.
Well Infrared is a wavelength slightly longer than visible light and its also known as radiant heat - to infrared light is mostly heat, just like in the movie Predator Schwarzenegger.
