Homework Help: Deriving the Wein displacement law

  1. Mar 6, 2013 #1

    I am not really sure where to go from here, since T varies. I am guessing this means I am approaching the problem incorrectly, but in that case, I have no idea how to do it. Any help/guidance would be appreciated.

    Looks like an error in computing dI/dλ.

    d/dx eu = eu du/dx.

    If u = a/x, d/dx eu = (-a/x2)ea/x, not (a)ea/x.
