Solving a problem in physics, section 51, point 59 wave

59. In the vacuum along the x axis plane electromagnetic wave propagates. The amplitude of the electric field of the wave is 18.8 V / m. To determine the intensity of the wave, ie, average energy per unit time per unit area, perpendicular to the direction of wave propagation.
