A plane electromagnetic wave broadcast by Stockton's 99.3 KJoy FM at a 99.3 MHzmoves in the positive y-axis direction such that its electric field is pointed along the z-axis.The amplitude of the electric field is 1.41 V/m. The start of time is chosen so that at t=0,the electric field has a value 1.41 V/m at the origin. a. Write the wave function that will describe the electric field wave. b. Calculate the amplitude the associated magnetic field wave. c. Calculate the intensity of the radio wave.
