# Eureka!

An incandescent light bulb in a room with an air temperature of $$300~\mbox{K}$$ radiates with a peak wavelength of $$10^{-6}~\mbox{m}$$. The bulb draws $$0.5~\mbox{Amperes}$$ from the $$120~\mbox{Volt}$$ wall electrical outlet. What is the surface area of the filament in the bulb in $$\mbox{m}^2$$?

Assumption

The filament may be modeled as a perfect "black body".
