Just consider the blackbody radiation
curve for 3 K, whose peak is located at wavelength of 1 mm.
This property is described by Planck's blackbody radiation
3]) [delta] = thickness, m (in) [epsilon] = emissivity [sigma] = blackbody radiation

2] output power couple times over blackbody radiation
up to temperature 400K.
But I thought that classical physics fell precisely due to the "ultraviolet catastrophe" when the Rayleigh-Jeans formula failed to predict the drop in frequency of blackbody radiation
at higher temperatures.
The PIRELC, a high-output emitter from Cal Sensors can be used as a steady state or pulsed source of blackbody radiation
for near-to-far infrared applications.
This structured emission is easily distinguished from the featureless blackbody radiation
of the underlying material stream.
These devices often must be exposed to blackbody radiation
sources that accurately characterize the response of the device.
Electrical output of these structures, within a superheated vacuum, yielded a conversion efficiency of 34%, three times the predicted values governed by ideal blackbody radiation
The energy captured by the planet is assumed to warm the planet until the energy radiated through blackbody radiation
is equal to that received from its sun.
The P310 precision blackbody radiation
calibration source has a 76-mm aperture opening and employs a highly conductive copper cone-shaped cavity that, according to the manufacturer, achieves an emissivity value of 0.
The IR emissivity of real-world materials is defined in terms a percentage of blackbody radiation
at a given temperature.
However, the study of blackbody radiation
at thermal equilibrium led to experimental results that could not be explained by classical electromagnetic theory.
The seven activities focus on star mass, modeling a black hole, classifying stars, blackbody radiation
, Wein's Law, and crossing the event horizon.
Microwave radiometers, which measure natural blackbody radiation
, can measure ocean salinity, and the age and thickness of sea ice.
