Jan 20, 2025 · 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 radiation can be used to remotely determine the temperature of objects (if the emissivity is known). This is termed thermography, or in the case of very hot objects in the NIR or visible it is termed pyrometry. Thermography (thermal imaging) is mainly used in military and industrial applications but the technology is reaching the ...

Aug 10, 2016 · 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.

Infrared radiation is a region of the electromagnetic radiation spectrum where the range of wavelengths is from about 700 mn to 1 mm. Learn about the applications and medicinal effect of infrared rays at BYJU'S

Feb 27, 2019 · Infrared radiation (IR), or infrared light, is a type of radiant energy that's invisible to human eyes but that we can feel as heat. All objects in the universe...

Infrared radiation (IR), sometimes referred to simply as infrared, is a region of the electromagnetic radiation spectrum where wavelengths range from about 700 nanometers (nm) to 1 millimeter (mm). Infrared waves are longer than visible light waves but shorter than radio waves.

Apr 30, 2024 · Infrared (IR) is a type of electromagnetic radiation that has longer wavelengths than visible light, making it invisible to the human eye. It falls just beyond the red portion of the visible spectrum, hence its name meaning "below red."

Aug 16, 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.

Infrared radiation (IR) is a type of radiant energy, with longer wavelengths than the visible light humans can see, but shorter wavelengths than radio waves. Its range extends from fairly small wavelengths near the color red, 700x10 -9 m, to nearly a millimeter, 3x10 -4 m. [2]

Jan 24, 2025 · Infrared radiation is a region of the electromagnetic radiation spectrum where wavelengths range from about 700 nm to 1 mm. Learn its discovery, sources, & uses. English Get Started
