Infrared radiation (IR), sometimes known as infrared light, is electromagnetic radiation (EMR) with wavelengths longer than those of visible light. Hence, it is undetectable by the human eye, although IR of wavelengths up to 1050 nanometers (nm) from specially pulsed lasers can be seen by humans under certain conditions.

Infrared ( IR; sometimes called infrared light) is electromagnetic radiation (EMR) with wavelengths longer than that of visible light but shorter than microwaves. The infrared spectral band begins with waves that are just longer than those of red light (the longest waves in the visible spectrum ), so IR is invisible to the human eye.
Aug 10, 2016 · Learn what infrared waves are, how they were discovered, and how they are used to study the universe and the Earth. See examples of infrared images of planets, stars, nebulae, aurorae, and more.
Jun 26, 2024 · Infrared Waves are electromagnetic waves that have frequency range between 300 GHz to 400 THz. These cannot travel along long distances. These waves are used for short range communication and they also use line-of-sight of propagation.
3 days ago · 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.
