In an electromagnetic light wave, the electric and magnetic fields are arranged as transverse waves, meaning they oscillate in directions perpendicular to the direction of wave propagation.1

Furthermore, the electric field and magnetic field are perpendicular to each other. Together, the directions of the electric field, the magnetic field, and the wave propagation form a right-handed coordinate system. These fields are also in phase with one another, meaning that at any given point in space, they reach their maximum values at the same time.1

In a vacuum, the amplitudes of these fields are related by the equation $E_{0} = c B_{0}$ , where $c$ is the speed of light. Because the magnetic field's orientation is constrained by the requirement that it remain perpendicular to both the electric field and the direction of propagation, it is standard practice to specify only the direction of the electric field when describing the wave's orientation.1
