Planck function

  1. Mar 6, 2014 #1
    I came across this question and though I've looked it up but I haven't found anything concrete and in truth confuses me more. It was posed by my lecturer and it is:

    For the Planck function Bv(t), what is the most probable frequency vp at a given temperature? Similarly for the Planck function Bλ(t), what is the most probable wavelength λp at a given temperature and are the two results consistent with each other?

    I know for the second one that I need dB/dλ = 0 but then what do I do? Detailed help would be most appreciated :)
