Stefan-Boltzmann and Wien's law

Postby Emily Kennedy 4L » Fri Oct 12, 2018 5:18 pm

Both Boltzmann's and Wien's law have to do with wavelength corresponding to intensity as the temperature increase so in what instances would you use the equations that correspond to the laws?

Boltzmann's law is when total intensity is proportional to T^4 while Wien's law is when T is inversely proportional to wavelength of maximum intensity so you use Wein's law for cases involving wavelength whereas Boltzmann's law is used when only total intensity is involved and not wavelength.

I have a follow-up question that is related to this previous question:
what is the relationship between the Stefan-Boltzmann law (total intensity = constant x T^4) and Wien's law (TAmax = constant)? I'm confused as to how these laws are related when we are talking about inverse proportionality and the temperature.
