Infrared - Wikipedia
Infrared (IR; sometimes called infrared light) is electromagnetic radiation (EMR) with wavelengths longer than that of visible light but shorter than microwaves.
What Is Infrared Light and How Does It Work? - ScienceInsights
Infrared light is a type of electromagnetic radiation with wavelengths longer than visible red light, ranging from about 700 nanometers to 1 millimeter. You can’t see it with your eyes, but you feel it every day as warmth.
Infrared radiation | Definition, Wavelengths, & Facts | Britannica
infrared radiation, that portion of the electromagnetic spectrum that extends from the long wavelength, or red, end of the visible-light range to the microwave range. Invisible to the eye, it can be detected as a sensation of warmth on the skin.
Infrared Light - Infrared Radiation - Science Notes and Projects
Infrared light, also called infrared radiation or IR waves, is a type of electromagnetic radiation with wavelengths longer than visible light but shorter than microwaves. It is invisible to the human eye but can be felt as heat.
Infrared Waves - NASA Science
Infrared waves have longer wavelengths than visible light and can pass through dense regions of gas and dust in space with less scattering and absorption. Thus, infrared energy can also reveal objects in the universe that cannot be seen in visible light using optical telescopes.

Electromagnetic spectrum - Wikipedia
A rainbow shows the optical (visible) part of the electromagnetic spectrum; infrared (if it could be seen) would be located just beyond the red side of the rainbow whilst ultraviolet would appear just beyond the opposite violet end.
Infrared Astronomy - NASA Science
Some bodies of matter that are cool and do not emit much energy or visible brightness, like people or a young planet, still emit infrared light. Humans perceive this as heat, while some other animals, like snakes, are able to “see” infrared energy.
What Is Infrared Light? Definition & Top Uses - Optics Mag
Infrared is a type of energy on the electromagnetic spectrum. Invisible to the human eye, infrared energy is given off by all heat sources. Discovered in 1800 by William Herschel, infrared can be detected using instruments like night-vision goggles and infrared cameras.
INFRARED Definition & Meaning - Merriam-Webster
The meaning of INFRARED is situated outside the visible spectrum at its red end —used of radiation having a wavelength between about 700 nanometers and 1 millimeter.
