Is this black body radiation considered light?
PS: Sorry, I spelt emit wrong:(

How does N2 gas radiate
Blackbody radiation is radiation emitted by a black body. A black body absorbs all incoming electromagnetic radiation.Studiot said:Naty I think you are confusing different phenomena.
There are two meanings to the term in Physics. 'blackbody radiation' and 'a black body'
Post #2 and the above reiteration are wrong. Blackbody radiation is an idealization. No real body emits thermal radiation that perfectly follows the blackbody spectrum.Post#2 is correct, all bodies at the same temperature emit radiation (=light etc) of the same spectrum.
Black body radiation is a type of electromagnetic radiation that is emitted by all objects at a certain temperature. It is named "black body" because it is the idealized radiation that is emitted by a perfect black body, which absorbs all radiation that falls on it.
Yes, all bodies emit black body radiation as long as they have a temperature above absolute zero. This is because the movement of particles within the body causes them to emit photons, or particles of light, which make up the radiation.
The amount and frequency of black body radiation emitted by a body is directly related to its temperature. As the temperature of a body increases, the amount of radiation emitted also increases, and the peak wavelength of the radiation shifts to shorter wavelengths.
Black body radiation is used in a variety of scientific fields, including astrophysics, thermodynamics, and materials science. It is used to study the properties of different materials, as well as to understand the behavior of stars and other celestial bodies.
Yes, black body radiation can be observed in everyday life. For example, the heating element on a stove emits black body radiation as it heats up, and the glow of a fire is also a form of black body radiation. Infrared cameras are also able to detect black body radiation, which is used for thermal imaging purposes.
