Where does the heat come from in a volcano?
Infrared lies between the visible and microwave portions of the electromagnetic spectrum. Infrared waves that are near to visible light do not generate heat and are used in TV remote controls. Infrared waves that are far from the visible end of the light spectrum are thermal and generate heat. The infrared heat from the sun, a lamp or a radiator is a type of far infrared radiation.
What electromagnetic wave can be used to map wildfire obscured by smoke?
far infrared
Why are near infrared telescopes located on mountaintops and ultraviolet telescopes in Earth orbit?
The primary infrared blocker, water vapor, is mostly in the lower atmosphere and the primary ultraviolet blocker, ozone, is located high in the atmosphere, far above mountaintops.
EM radiation often emitted by heat lamps heaters and fires?
That would be the portion of the spectrum called "heat" (far infrared).
Why does an incandescent light bulb produce a continuous spectrum that seems to favor red?
Actually the peak of the radiation from an incandescent light bulb is in the near infrared, not the visible spectrum. The visible light that you see is the falling upper sideband of this: very strong in the red and declining until it is weak in the blue and violet end with a very small amount of radiation in the ultraviolet. The lower sideband extends across the infrared and into the far infrared. Well under a third of the emitted electromagnetic radiation of an incandescent light bulb is visible light, most is infrared.
Why must telescopes observing at far- infrared wavelengths be cool to low temperatures?
Far infrared Astronomy is the branch of astronomy and astrophysics which deals with objects visible in far-infrared radiation. The cold telescope allows the equipment to work properly
What is the distance covered by infrared radiation?
Like any other electromagnetic wave, there is no limit how far infrared can go.Like any other electromagnetic wave, there is no limit how far infrared can go.Like any other electromagnetic wave, there is no limit how far infrared can go.Like any other electromagnetic wave, there is no limit how far infrared can go.
What wavelengths are in heat lamps?
Although they do have some visible light, heat lamps skew towards the infrared end of the spectrum. Heat lamps are designed to emit light in the Near Infrared (.7µm-1.3µm), Middle Infrared (1.3µm-6µm), Far Infrared (6µm-40µm), and Far-Far Infrared (40µm-1000µm)
Why would one need to use far infrared?
Far infrared therapy is a relatively new development in health care products. Far infrared therapy is used in cancer treatment as well as in hyperthermic therapies for detoxification.
Where can you buy far infrared gloves in the EU?
I found www.shopofdeal.com who has some far infrared items including gloves and blankets for sale.
How far can infrared light reach?
Infrared light is just light of a specific wavelength it can travel as far as any other wavelength of light.
Do infrared waves interact with the ozone?
Yes. It has some absorption in the "far infrared", about 11,000 nanometers.

Are there dangers in using an far infrared sauna?
Not really, infrared saunas are safe. The same infrared heaters are used on baby incubators to keep them warm.
Are infrared rays absorbed by the ozone layer which protects the earth?
Far infrared rays are, corresponding to lower temperatures, but not near infrared which corresponds to warmer temps.
What are infrared lights?
== == Infrared light lies between the visible and microwave portions of the electromagnetic spectrum. Infrared light has a range of wavelengths, just like visible light has wavelengths that range from red light to violet. "Near infrared" light is closest in wavelength to visible light and "far infrared" is closer to the microwave region of the electromagnetic spectrum. The longer, far infrared wavelengths are about the size of a pin head and the shorter, near infrared ones are the size of cells, or are microscopic.
Are prison showers bad?
It depends on your definition and focus. As far as facilities go, they are generally adequate. As far as what happens in them, they are generally adequate--for allowing prisoners to maintain hygiene.
