Calculating energy from flux and max wavelength

  1. Sep 27, 2011 #1
    hey im calculating energy of a blackbody emitter, and i have the flux (energy per unit area) and the peak wavelength emitted. how do i calculate total energy?

    Since you have your peak wavelength, use Wein's Displacement Law to find the temperature of your black body emitter:

    [itex]\lambda[/itex][itex]_{max}[/itex] T = 2897.8 um-K

    Then apply Stepan-Boltzmann Law to find total power:

    E = [itex]\sigma[/itex] T[itex]^{4}[/itex].
