| Wien's Displacement Law |
|
|
The Wien's Displacement Law state that the wavelength
carrying the maximum energy is inversely proportional to the
absolute temperature of a black body. |
|
|
i.e λmax x T = b |
|
Where, λmax = Wavelength of maximum intensity ( meters )
T = Temperature of the blackbody ( kelvins )
b = Wien's displacement constant = 2.8977685
± 51 × 10-3 meters·kelvins |
|
For optical wavelengths, it is often more convenient to use
the nanometer in place of the meter as the unit of measure.
In this case,
b = Wien's displacement constant =
2.8977685 ± 51 × 106 nm·K |
|
|
The law is named after German physicist Wilhelm Wien.
