Infrared Waves Examples in Real Life. Infrared radiations are electromagnetic waves that are invisible to the human eyes. The value of the wavelength of infrared waves lies within the range 740 nm and 4 x {10}^ {5} 105 nm. The frequency band of infrared rays typically ranges between 300 GHz and 400 THz. In the electromagnetic spectrum, the ...
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.
Within the electromagnetic spectrum, infrared waves occur at frequencies above those of microwaves and just below those of red visible light, hence the name "infrared."
In this lesson, learn about infrared waves and find examples of infrared wave uses. See how humans have invented equipment that can utilize infrared radiation. Updated: 11/21/2023.
Infrared waves have therapeutic uses in thermotherapy, where they are used to alleviate pain and inflammation in the body. Heat therapy using infrared waves is known to have a deeper penetration into the skin, helping to increase blood flow and relaxation of muscles.
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. Learn more about infrared radiation in this article.
Radiation, including visible light, comes in waves of different lengths. Some of those lengths — including infrared — are too long for our eyes to perceive them. Infrared light gets its name from the fact that these wavelengths are a bit longer than what we see as the color red.
Infrared (IR) waves, a type of electromagnetic radiation with wavelengths longer than visible light but shorter than microwaves, are integral to a myriad of applications beyond the commonly known uses in household appliances, television remotes, and intruder alarms.
For light, it is the length of one full cycle, or pulse, of the electric and magnetic fields. A related property is the frequency, or the number of waves that pass a fixed point every second. Infrared light that falls on your skin will cause it to warm up, and you will feel the heat.
Two activities help students learn about infrared light and the relationship between wavelength and energy.
