The Tungsten filament of an incandescent lightbulb is a wire of diameter=0.080mm and length=5.0cm at a temperature of 3200K. What is the power radiated by the filament? We Know: Power=Watt/time=Energy/time' E=h(nu) nu=5.088E10 Hz/K I'm not sure how to use the diameter and length to find the power. Since it's a filament, it would be in the shape of a cylinderso we could use the information to find the area, but I don't know how that applies. Any help is appreciated!
