Electromagnetic waves

The picture represents a plane wave (at every instant of time, the electric magnetic field vectors are uniform over any plane perpendicular to the x-axis) Assuming that the change in x is small enough so that the magnetic flux is nearly uniform over the rectangle gfhe, what relationship can be proven using only the picture

The wave speed in a vacuum is approximately 3 x 10^8 m/s The ratio of Magnetic field to Electric Field on the same boundary plane is equal to 3.00 x 10^8 m/s The Poynting Vector is in the direction of the propagation of an electromagnetic wave A time varying electric field guarantees a x-varying magnetic field
