We can reasonably model a 100-W incandescent lightbulb as a sphere 6.0cm in diameter. Typically, only about 5% of the energy goes to visible light; the rest goes largely to nonvisible infrared radiation. A) What is the visible light intensity at the surface of the bulb?B) What is the amplitude of the electric field at this surface, for a sinusoidal wave with this intensity?C) What is the amplitude of the magnetic field at this surface, for a sinusoidal wave with this intensity?
