A strong light bulb radiates light in all directions. The average power of the EM waves by this bulb is 1910.0 W. At a distance r = 0.6 m from the bulb, the EM waves spread over a surface area of 4πr2 (a) Calculate the Average Intensity. Keep 1 decimal place. (b) Calculate the Average Energy Density (including both the electric field...
