A 60W light bulb emits spherical electromagnetic waves uniformly in all directions. If 50 percent of the power input to such a light bulb is emitted as electromagnetic radiation, what is the radiation intensity at a distance of 2:00 m from the light bulb?

1) 4:8W/m²
2) 1:2W/m²
3) 2:4W/m²
4) 0.6W/m²
