An electromagnetic wave generator in a vacuum emits radiation that at very long distances It can be considered as a flat wavefront. For a certain observer, waves have a electric field given by: Picture 2.1 and the average power with which radiation falls on a plane with an area of 2.0 m2 is 2.554 × 1017 W, with an angle of incidence of 45°. Suppose the Poynting vector points in the direction of the positive ?-axis 1. Calculate the value of the wavelength, the angular frequency and ?0. 2. Write the corresponding vector equation for the electric field of this wave, as a function of position and time, in terms of the numerical values calculated in the previous point.
