Unformatted text preview: Extra 3 You have a black body at temperature T and can not remember Wien’s displacement law that relates T to the frequency of maximum emission ν max . You want to come up with a close alternative to ν max and decide to ﬁnd ν alternative through hν alt = kT. (5) Calculate by what factor is ν max smaller or larger than ν alt . If this factor is not so large (less than 10) then you found an easy way to approximate ν max . 1 Extra 4  Optional Using the two expressions for the ﬂux of a black body, one as a function of frequency and the other as a function of wavelength, derive two expressions for the Wien displacement law. For a ﬁxed temperature T , does ν max λ max = c ? Give a reason for either answer. 2...
