How is this derived?

  1. R=[tex]\epsilon[/tex][tex]\sigma[/tex]T[tex]^{4}[/tex]

    [tex]\epsilon[/tex] --> emmisivity
    [tex]\sigma[/tex] --> Steffan's constant
    T[ --> Temp (in Kelvin)

    should i start with steffan-boltzmann's equation (since its the nearest formula)?

    thanks... ^_^

    Actually, I think that already is the Stefan-Boltzmann law; if you start from it you're done.

    There is a derivation here, though generally I always check derivations on Wikipedia before I trust them :smile:
     
  4. oh... im sorry. i feel noobish! haha!
