(a) The electric field of an electromagnetic wave propagating in free space is described by the equation E(z, t) = Eo[êsin(kz – wt) + ŷcos(kz – wt)] where ^x and ^y are unit vectors in the x- and y-direction, respectively. What is this wave’s direction of propagation? What is the polarization of the wave?
