The power per unit area emitted by a blackbody is given by P = T 4
Question:
The power per unit area emitted by a blackbody is given by P = σ T4 with σ = 5.67 × 10−8 W m−2 K−4. Calculate the power radiated by a spherical blackbody of radius 0.500 m at 925 K. What would the radius of a black body at 3000. K be if it emitted the same energy as the spherical blackbody of radius 0.500 m at 925 K?
