Infrared Waves: Definition, Uses & Examples The electromagnetic spectrum contains many types of waves, one of which is infrared waves. Other electromagnetic waves include gamma rays, x-rays, ultraviolet, visible light, microwaves, and radio. Infrared waves are electromagnetic radiation of a particular wavelength or color that we have named 'infrared.' They are between 700 nm (nanometers) and 1 mm. Note that 1 mm is equal to 1,000,000 nanometers. They are just beyond what our eyes can detect on the red side of the rainbow.

Heat Radiation The energy radiated by solids, liquids, and gases as a result of their temperature. Such radiant energy is in the form of electromagnetic waves and covers the entire electromagnetic spectrum, extending from the radio-wave portion of the spectrum through the infrared, visible, ultraviolet, x-ray, and gamma-ray portions.

Infrared Waves The infrared radiation or waves can be defined as waves with the wavelength in the range of 0.75 µm to 1 mm in the EM spectrum. The infrared waves are of wavelength well below the visible region of the EM spectrum.The infrared are not visible to our eye since they are outside the narrow window of the visible frequencies. In other words, we can say that we are blind for all the spectrum except the visible spectrum.he infrared waves are of wavelength well below the visible region of the EM spectrum.

Infrared Radiation - Warmth From The Cold of Space Radiation in the Electromagnetic Spectrum is often categorized by wavelength. Short wavelength radiation is of the highest energy and can be very dangerous - Gamma, X-rays and ultraviolet are examples of short wavelength radiation. Longer wavelength radiation is of lower energy and is usually less harmful - examples include radio, microwaves and infrared.

infrared radiation (IR) infrared radiation (IR) Infrared radiation (IR) or the term infrared alone refers to energy in the region of the electromagnetic radiation spectrum at wavelengths longer than those of visible light,but shorter than those of radio waves. Correspondingly, the frequencies of IR are higher than those ofmicrowaves, but lower than those of visible light.

How is infrared radiation different from visible light? Confidence votes 37.3K. Infrared radiation has a slightly longer wavelength than visible light. The name infrared means less than red, and it is just beyond visible red light, on the spectrum. The wavelength is longer, but the frequency is lower, which is where the less than comes from. It is also less energetic. The energy content of electromagnetic radiation is directly proportional to the frequency.

Infrared and Radiant Heating Infrared and Radiant Heating. Infrared heating is the transfer of energy via electromagnetic radiation between a source and an object. Most materials absorb heat in the infrared wave band with useful wavelengths for industrial applications in the 3 to 8 micron ranges. Radiant heating (electric, gas, steam, oil) is often used for drying textiles, ceramics, paint (wood and metal), hardening powder paint and heat treatment of plastics.

Thermography Infrared thermography (IRT) , thermal imaging, and thermal video are examples of infrared imaging science. Thermographic cameras usually detect radiation in the long-infrared range of the electromagnetic spectrum (roughly 9,000–14,000 nanometers or 9–14 µm) and produce images of that radiation, called thermograms.

Infrared Radiation: Definition, Uses & Effects Lesson Summary. Infrared radiation is made up of electromagnetic waves with a wavelength between 700 nm (nanometers) and 1 mm, just beyond what our eyes can detect on the red side of the spectrum. Most warm objects in our everyday experiences emit infrared, and half of the energy produced by the Sun is also infrared.his lesson will explain what infrared radiation is, and discuss a number of practical uses and effects of infrared, including its connection to climate change and the way the atmosphere responds to infrared waves.

Heat Radiation Heat Radiation. a form of electromagnetic radiation emitted by a substance as a result of its internal energy. Heat radiation is contrasted, for example, to luminescence, which results from external energy sources. Heat radiation has a continuous spectrum whose maximum is a function of the temperature of the substance.

Physics for Kids Infrared waves are sometimes classified as near infrared and far infrared. Near infrared waves are the waves that are closer to visible light in wavelength. These are the infrared waves that are used in your TV remote to change channels. Far infrared waves are further away from visible light in wavelength. Far infrared waves are thermal and give off heat.

Infrared Radiation The only way to study the entire range of infrared (as well as gamma rays, xrays, UV) is to place telescopes in space well above the atmosphere. Only some (not all) of the IR radiation between 1 and 40 microns makes it to the Earth's surface. The rest is absorbed by our atmosphere primarily by water vapor.

Blue Light: It's Both Bad And Good For You Rays on the blue end of the spectrum have shorter wavelengths and more energy. The electromagnetic rays just beyond the red end of the visible light spectrum are called infrared — they are warming, but invisible. (The warming lamps you see keeping food warm at your local eatery emit infrared radiation.
