Wavelength of Maximum
The wavelength at which a perfect radiator emits the maximum amount of energy; depends only on the object's temperature.
White Dwarf Stars ...

 


wavelength of maximum intensity: The wavelength at which a perfect radiator emits the maximum amount of energy; depends only on the object's temperature.

where is the wavelength of maximum intensity; b is a constant; and T is the absolute temperature. The Wien displacement constant b is equal to 0.28978 centimeter-degree. Also called Wien displacement law .

black-body radiation at a given temperature, as a function of wavelength; (c) the Stefan-Boltzmann law relates the time rate of radiant energy emission from a black body to its absolute temperature; (d) the Wien law relates the wavelength of maximum ...

The value of Wien's relationship is that if you can measure the wavelength of maximum intensity from a spectrum, you can use it to calculate a value for the effective temperature. let us see how this works in the example below.

An experimentally discovered law applicable to thermal continuum radiation, which states that the wavelength of maximum emission intensity is inversely proportional to the absolute temperature.
Wm-2 (or W/m2 ) - (n.) ...

Thus at 6000 K, the wavelength of maximum intensity is 0.29/6000 cm, or 480 nm, corresponding to the yellow-green part of the visible spectrum. (Recall that 1 nanometer"1 nm"is equal to 10-9 m; see Appendix 2.) ...

The pressure from degenerate electrons prevents further collapse. Wien's law relation between the wavelength of maximum emission in a thermal spectrum and its temperature: wavelength peak in nanometers = 2.9× 106/temperature in Kelvin.
