Find the visible light intensity at surface of bulb

Reference no: EM13678139

We can reasonably model a 90-W incandescent light bulb as a sphere 7.0 centimeter in diameter. Typically, only about 5 percent of the energy goes to visible light; the rest goes largely to no visible infrared radiation.

A) Find the visible light intensity at surface of bulb?

B) Find the amplitude of the electric field at this surface, for a sinusoidal wave with this intensity?

C) Find the amplitude of the magnetic field at this surface, for a sinusoidal wave with this intensity?
