 P: 19 R=$$\epsilon$$$$\sigma$$T$$^{4}$$ $$\epsilon$$ --> emmisivity $$\sigma$$ --> Steffan's constant T[ --> Temp (in Kelvin) should i start with steffan-boltzmann's equation (since its the nearest formula)? thanks... ^_^
 HW Helper Sci Advisor P: 4,281 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
 P: 19 oh... im sorry. i feel noobish! haha!
