* E = hf = hc/wavelength = (6.63 x 10-34 J*s)(3.00 x 108 m/s)/(25 x 10-6 m) = 7.9 x 10-21 J per photon. This is the energy of a photon at that wavelength. == The person who asked the question answered it. Why ask a question to which you already know the answer? And the body under "normal" conditions radiates infrared (IR) most strongly at about 10 micrometers.
By the emission of the terrestrial radiation. Terrestrial radiation is emitted in the infrared long-wavelength part of the spectrum. It is terrestrial radiation rather than solar radiation that directly warms the lower atmosphere.
Infrared radiation is when earths surface radiates some of earths surface back into the atmosphereinfrared radiation is a type of electromagnetic radiation, which involves waves rather than particles. This means that unlike conduction and convection radiation can even pass through the vacuum of space.infrared radiation is a form of electromagnetic radiation which is emitted in the form of heat. infrared radiation is invisible
yes
Yes - infrared radiation is heat. Glowing firewood emits heat (as well as visible light)
a decrease in the wavelength of radiation emitted by a celestial body as a consequence of the doppler effect
Infrared radiation is emitted by almost everything on Earth because almost everything is a temperature that will emit at that wavelength. Even you are emitting in the infrared.
The Earth emits thermal radiation of a much lower intensity in the infrared rather than visible region . The wavelength of infrared rays is around 10^-6 meter.
By the emission of the terrestrial radiation. Terrestrial radiation is emitted in the infrared long-wavelength part of the spectrum. It is terrestrial radiation rather than solar radiation that directly warms the lower atmosphere.
Yes, infrared radiation can detect heat. Infrared sensors are designed to detect and measure the infrared radiation emitted by objects, including heat emitted by living organisms or warm objects.

Yes. Since radiation includes infrared, which of course is emitted by an iron.
Short wavelength radiation such as Ultraviolet fall to absorption spectrum band of Ozone. Ozone absorb UV and re-emitted the radiation in the range of infrared or thermal range radiation.
No. While most infrared radiation is from the center of hot solid objects, some of it is not. The sun is plasma (not solid) and it emits infrared radiation. Also, infrared radiation can be emitted by the friction in between objects
Infrared radiation is invisible to us and emitted by the human body.
yes
Not as ultraviolet; the radiation is emitted as infrared radiation.
