Here's a breakdown:

* Changing Electric Field: When an electric field changes (either its strength or direction), it creates a magnetic field.

* Changing Magnetic Field: Conversely, a changing magnetic field creates an electric field.

These two phenomena are intimately linked and constantly reinforce each other. This interplay results in the propagation of an electromagnetic wave, where both electric and magnetic fields oscillate perpendicular to each other and to the direction of wave propagation.

Here are some key points to remember:

* The direction of the wave is determined by the direction of both the electric and magnetic fields.

* The speed of light is the speed at which electromagnetic waves travel in a vacuum.

* Electromagnetic waves encompass a wide spectrum of frequencies and wavelengths, including radio waves, microwaves, infrared radiation, visible light, ultraviolet radiation, X-rays, and gamma rays.

Think of it like a ripple effect in a pond: The changing electric field acts like the initial disturbance, and the magnetic field is the ripple that propagates outward.
