An electromagnetic plane wave at a certain location has an electric field pointed up which is given as a function of time as E = 54 V/m × sin (6x106 Hz × t). The magnetic field at the same location points south when the electric field points up. The wave is incident on a square piece of foil which is 3.6 m long on each side. If the wave is completely absorbed by the foil for 35 seconds, how much energy does the foil absorb?
