What is the electric field amplitude at a distance of 3.5 m from a 65 W lightbulb? Assume all the power of the bulb goes into light of a single color with λ = 500 nm and assume the bulb produces a spherical wave.
We can reasonably model a 120-W incandescent light-bulb as a sphere 6.5 cm in diameter. Typically, only about 6% 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? W/m2 (b) What are the amplitudes of the electric and magnetic fields at this surface, for a sinusoidal wave with this intensity? Emax = V/m Bmax =
