## Main Question or Discussion Point

In the book "Introduction to the structure of matter" by Brehm and Mullin, page 78. They say "It should be empathized that there is no reason for the peak positions [tex]\mu _m[/tex] and [tex]\lambda _m[/tex] in the respective distributions to be connected by the relation [tex]c=\mu \lambda[/tex]. They are talking about the blackbody frequency and wavelength spectra. On a graph the independent variable would be either [tex]\mu[/tex] or [tex]\lambda[/tex] and the dependent variable, [tex]M_ \mu (T)[/tex] or [tex]M _\lambda (T)[/tex].

I do not understand at all how, for a given temperature, a body would emit a peak of frequency [tex]\mu _m[/tex] that does not correspond to a peak of wavelength given by the formula [tex]\lambda _m =\frac{c}{\mu _m}[/tex].

Can you explain to me what's going on?
