A plane electromagnetic wave of frequency 34.0 GHz moves in the positive y-axis direction such that its electric field is pointed along the +z-axis. The amplitude of the electric field is 15.0 V/m. The start of time is chosen so that at = 0, the electric field has a value 15.0 V/m at the origin. [15] a. Write the wave function that will describe the electric field wave. b. Find the wave function that will describe the associated magnetic field wave. c. What is the average intensity of this wave?
