A butane torch is a tool in which butane is burned to create a flame. A detector, located at 2meters from the flame, only measures the flux of green photons (λ=500[nm]). At a certain moment, the detector measures a photon flux of ϕ(500nm)=3.37⋅1025[s−1⋅m−2]. For simplicity, assume that the flame behaves like a black body and has a spherical shape with a radius of 15cm, while the detector radius is 5cm. What is the temperature of the butane flame in?
