The temperature of stars other than the Sun can be approximated using a similar means by treating the emitted energy as a black body radiation.
22.
In 1804, Leslie observed that a matte black surface radiates heat more effectively than a polished surface, suggesting the importance of black body radiation.
23.
QTH : quartz tungsten halogen lamps offer spectra which very closely match black body radiation, although typically with a lower color temperature than the sun.
24.
Heat escapes the device by black body radiation from the anode ( plate ) as infrared radiation, and by convection of air over the tube envelope.
25.
Or is it a spectrum of energies, related to Black body radiation ?-- talk ) 16 : 10, 26 November 2012 ( UTC)
26.
Formally, Wien's displacement law states that the spectral radiance of black body radiation per unit wavelength, peaks at the wavelength ? max given by:
27.
Carbon rich exhausts from kerosene fuels are often orange in colour due to the black body radiation of the unburnt particles, in addition to the blue Swan bands.
28.
Generally this leads to a loss of energy at the outer surface of the spheromak though black body radiation, leading to a thermal gradient in the spheromak itself.
29.
"' Wien's displacement law "'states that the black body radiation curve for different temperatures peaks at a wavelength inversely proportional to the temperature.
30.
This expression was derived by Planck, and involves quantization of energy levels and black body radiation .-- HappyCamper 16 : 32, 8 February 2006 ( UTC)
