Homework Help: Thermal radiation

  1. Oct 5, 2012 #1
    Consider a 47000K object that emits thermal radiation.

    How much power does it emit per square meter?

    What is its wavelength of peak intensity?


    What formula do I use to solve these questions?

    How about trying Stefan-Boltzmann's law?

    Were you taught any topics prior to being given this problem?
