FThe light bulb in a room gives out 1 W of Power, as the only light source in this room. What is the irradiance measured at distances of 2 m and 4 m from it? What are the magnitudes of the electric field and magnetic fields at these distances, respectively? (Note: assume the light bulb size is much smaller than 1 m, thus can be treated as point source.)
