Examples of blackbody
blackbody
Hawking radiation is the hypothetical blackbody radiation emitted by black holes.
From the en.wikipedia.org
Or does it have a spectrum more like blackbody radiation in thermodynamics?
From the fredbortz.scienceblog.com
The black hole acts as a perfect blackbody radiating at this temperature.
From the en.wikipedia.org
This excess is thermal emission, also known as blackbody radiation.
From the sciencedaily.com
In 1900, Max Planck published his explanation of blackbody radiation.
From the en.wikipedia.org
The emission from a blackbody is usually considered as the maximum that an object can radiate.
From the sciencedaily.com
The black line is the emission power from an ideal blackbody with the same area as the carbon dot.
From the nature.com
The blackbody radiation graph is also compared with the classical model of Rayleigh and Jeans.
From the en.wikipedia.org
An almost perfect blackbody spectrum is exhibited by the cosmic microwave background radiation.
From the en.wikipedia.org
- Black body: a hypothetical object capable of absorbing all the electromagnetic radiation falling on it; "a black body maintained at a constant temperature is a full radiator at that temperature because the radiation reaching and leaving it must be in equilibrium"
- In physics, a black body is an idealized object that absorbs all electromagnetic radiation falling on it. Blackbodies absorb and incandescently re-emit radiation in a characteristic, continuous spectrum. ...
- A hot body with an incandescent black surface at a certain temperature used as a standard for comparison. Note that a black surface is the best radiator possible. A tungsten filament will emit slightly less radiation than a blackbody at the same temperature.
- A body with a surface emissivity of 1. Such a body will emit all of the thermal radiation it can (as described by theory), and will absorb 100% of the thermal radiation striking it. Most physical objects have surface emissivities less than 1 and hence do not have blackbody surface properties.
- An object that absorbs all incident radiation regardless of spectral or directional composition. A black body will also radiate energy at a rate expressed by the Stefan-Boltzmann Law with a spectral distribution expressed by Planck's radiation equation
- The ideal, perfect emitter and absorber of thermal radiation. It emits radiant energy at each wavelength at the maximum rate possible as a consequence of its temperature, and absorbs all incident radiance.
- A hypothetical object that is a perfect absorber and emitter of radiation.
- Instrument that provides a temperature source for on-site or in laboratory calibration of radiation thermometers.
- An ideal radiator whose radiant emittance, W, follows the Stefan-Boltzmann law. The relationship is shown below.
