i have a quick question, which hopefully someone can straighten out for me.
i was reading this http://en.wikipedia.org/wiki/Rayleigh-Jeans_law
at the part titled 'Consistency of frequency and wavelength dependent expressions'
i follow the logic, but am confused about where the - sign goes after the differentiation.
they differentiate, and get the negative, but when this is multiplied by the frequency dependent form, it disappears.
and i now know this cannot be a typo, because i have found other references which also have the answer as a positive.
could someone please explain where this negative goes, and for what reason.
thanks :)
