**wavelength of maximum intensity** (Î"max) (80) The wavelength at which a perfect radiator emits the maximum amount of energy. Depends only on the object's temperature.

weight (47) The force that gravity exerts on an object.

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 .

describes the variation of intensity of 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 intensity** ...

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.

However, the law is most commonly stated in terms of wavelength and is probably easier to remember that way. 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.
