A traveling electromagnetic wave in a vacuum has an electric field amplitude of 74.5 V/m. Calculate the intensity S of this wave. Then, determine the amount of energy U that flows through area of 0.0285 m 2 over an interval of 13.3 s, assuming that the area is perpendicular to the direction of wave propagation.
