3. A harmonic wave propagating along +z has its complex field expression given by Ê = ʸ⸠+ jʸâ¸, where Eo is a constant electric-field amplitude. What is the polarization state of this wave (linear, right-hand/left-hand circular/elliptical polarization)? Prove your answer.

A plane electromagnetic wave varies sinusoidally at 90.0 MHz as it travels throughvacuum along the positive x direction. The peak value of the electric field is 2.00 mV/m,and it is directed along the positive y direction.(i) Find the wavelength and period of the wave.(ii) Determine the maximum value of the magnetic field.(iii) Write expressions for the space and time variations of the electric field andmagnetic field vectors.(iv) Find the average power per unit area this wave carries through space.(v) Find the average energy density in the radiation.
