The Wavelength of a Black body calculator compute the wavelength of the strongest emissions from a black body based on its temperature.

INSTRUCTIONS: Choose units and enter the following:

• (T) This is the temperature of the black body

Wavelength (λ): The calculator returns the wavelength (λ) in nanometers.  However, this can be automatically converted to other length units (e.g. angstroms) via the pull-down menu.

#### General Information

A black body at a fixed temperature emits most strongly at a particular wavelength that depends only on the temperature. This formula describes that relationship. Formally, Wien's displacement law states that the spectral radiance of black body radiation per unit wavelength, peaks at the wavelength λmax.  Therefore the formula for the temperature of a black body is::

 T = b /( λ_max)
