It was discovered with a thermometer placed under the sun rays beyond the red end of the spectrum.
Humans emit infrared radiation, which is a type of electromagnetic radiation that is invisible to the human eye but can be felt as heat.
Infrared is not a color, but rather a type of electromagnetic radiation that is invisible to the human eye.
A hot iron emits infrared radiation, which is a form of electromagnetic radiation that is invisible to the human eye but can be felt as heat.
Hot things give off infrared radiation, which is a form of electromagnetic radiation that lies within the infrared region of the electromagnetic spectrum. This type of radiation is invisible to the human eye but can be felt as heat on the skin.
Invisible radiation refers to electromagnetic waves that are not visible to the human eye, such as ultraviolet light, X-rays, and gamma rays. Although these forms of radiation cannot be seen, they can have various effects on living organisms and materials. Protection measures are often required when working with invisible radiation to prevent harmful exposure.
because they are present at the invisible portion of the electromagnetic spectrum
It is a form of electromagnetic radiation.

The electromagnetic radiation (excluding the visible range) that pervades the universe.
True. Light energy is electromagnetic radiation that is invisible to the naked eye.
Radiation is the transfer of heat energy through space by electromagnetic radiation. Most of the electromagnetic radiation that comes to the earth from the sun is invisible. ... In electromagnetic radiation, its frequency is the number of electromagnetic waves moving past a point each second.
