A traveling electromagnetic wave in a vacuum has an electric field amplitude of 92.9 V/m. Calculate the intensity S of this wave. Then, determine the amount of energy U that flows through area of 0.0279 m² over an interval of 18.1 s, assuming that the area is perpendicular to the direction of wave propagation. S = W/m? U = J
