Question 9 Can the following electric fields represent the electric field of an electromagnetic wave in vacuum? Explain your reasoning. (a) E = E₁ exp[-i(k₁z - wt)]еz + E₂ exp[-i(k₂z - wt)]ex, where E₁, E2, w and k₁ #k₂ are all constants. (b) E = E₁ exp[-i(kz - wt)]e + E₂ exp[-i(kx - wt)]ey, where E₁, E2, w and k are all constants.
