A plane electromagnetic wave, which has an electric field E(X, t) = (P + Q) exp iw (1-) is passing through vacuum. Here P, Q and w are all constants, while c is the speed of light in vacuo. What is the average energy flux per unit time (in S1 units) crossing a unit area placed normal to the direction of propagation of this wave, in terms of the above constants?
