Wien's displacement law states that the wavelength of highest intensity in the radiation from a blackbody is something like:(adsbygoogle = window.adsbygoogle || []).push({});

[tex] \lambda_{max} = \frac{2.898*10^{-3}}{T} [/tex]

in meters, where T is the temperature given in kelvins.

If you try to transform this law into frequency one would expect that we should have:

[tex] f_{max} = \frac{c}{\lambda_{max}} [/tex]

but apparently this is not the case!!! Why is it like that?

I mean, if you have a blackbody radiation field it will have a maximum of intensity at some frequency, but shouldn't that frequency coincide with the wavelenght for which it has the maximum intensity????

Please help!
