We can reasonably model a 90-W incandescent lightbulb as a sphere 5.5cm 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? answer in W/m^2

B) What is the amplitude of the electric field at this surface, for a sinusoidal wave with this intensity? answer in V/M

C) What is the amplitude of the magnetic field at this surface, for a sinusoidal wave with this intensity? answer in uT
