A light source radiates 60.0 W of single-wavelength sinusoidal light uniformly in all directions. What is the amplitude of the electric field of this light at a distance of 0.400 m from the bulb? (0 = 8.85 × 10-12 C2/N m2, 0 = 4 × 10-7 T m/A, c = 3.00 × 108 m/s) options are :     150 N/C     212 N/C     82.1 N/C     162 N/C     52.9 N/C
