infrared) – promieniowanie elektromagnetyczne o długości fal między światłem widzialnym a falami radiowymi. Oznacza to zakres od 780 nanometrów do 1 milimetra. Energia fotonów promieniowania podczerwonego zawiera się w przedziale od 0,001 eV do 1,6 eV, a częstotliwość drgań od 300 GHz do 400 THz.
Infrared radiation refers to electromagnetic radiation with wavelengths between microwave and visible light, ranging from 0.78 to 1000 μm. It is not directly visible to the human eye but is emitted by any object with a temperature above absolute zero.
16 sie 2013 · Infrared is a form of light... light that we can not see with our eyes, but that we can sometimes feel on our skin as heat. When we think of light, we may imagine the glare of the Sun on a summer day, or the soft glow of a light bulb at night.
