Wien's law
Wien's law or Wien law may refer to:
- Wien approximation, an equation used to describe the short-wavelength (high frequency) spectrum of thermal radiation
- Wien's displacement law, an equation that describes the relationship between the temperature of an object and the peak wavelength or frequency of the emitted light.
It can be stated as: "The product of the Thermodynamic temperature of black body in kelvin and the wave length of maximum displacement is always a constant" The constant is called Wien's constant value of which is 2.898*10^-3 mK)
