Assume all the power consumed by a 75 W light bulb is emitted by the filament, which you can treat as a black-body. Treat the filament as a cylinder of diameter 1.0 mm and length 2.0 cm. What is the peak wavelength of the lightbulb's emission spectrum? What energy is emitted per surface area (cm²) unit in each second? (show the solution!)
