Problem # p025 |

We wish to determine the temperature of the surface of a medium strength incandescent, frosted light bulb. To this end we assume :

- The material of the bulb's surface radiates like a black body

(Stefan-Boltzmann constant : σ=5.67*10^{-8}W/(m^{2}K^{4})

- We can neglect all other modes of energy loss except of course radiation

- The light bulb is a perfect sphere with a radius of R = 3.5 cm

(surface of a sphere : 4*π R^{2})

- The light bulb is rated at 100 W
