(10 marks) Consider a electromagnetic plane wave propagating along x-direction in vacuum, therefore both electric field and magnetic field are functions only of x and time t(i.e. vec(E)(x,t),vec(B)(x,t). Show that the electromagnetic wave in vacuum is transverse (i.e. there is no oscillation of electromagnetic field along the propagating direction).
