EM waves are defined as a propagating couple of an electric and magnetic field components whereby the electric and magnetic field vectors include an angle of 90 degree in the media we commonly find in POFs. The frequency f is the responsible physical value that determines the physical properties of EM waves * The speed of propagation of electromagnetic waves*. We can next apply Maxwell's equations to the description given in connection with (Figure) in the previous section to obtain an equation for the E field from the changing B field, and for the B field from a changing E field. We then combine the two equations to show how the changing E and B fields propagate through space at a speed precisely. The waves predicted by Maxwell would consist of oscillating electric and magnetic fields—defined to be an electromagnetic wave (EM wave). Electromagnetic waves would be capable of exerting forces on charges great distances from their source, and they might thus be detectable. Maxwell calculated that electromagnetic waves would propagate at a speed given by the equation

- This field satisfies a wave equation traveling at the speed of light. Hence, light is an electromagnetic wave. Light consists of photons; and thus each photon carries a unit of energy. This behavior is demonstrated by the photoelectric and Compton effects. Since light is an electromagnetic energy, photons must also carry electromagnetic field and a unit of it. While photons are quantum objects.
