Describe how electromagnetic waves are formed and travel through space.
Electromagnetic waves are formed by the vibration of a charged particle. This movement creates a changing electric field, which in turn generates a changing magnetic field perpendicular to it. These oscillating fields regenerate each other and propagate through space as a transverse wave, meaning they can travel even through a vacuum without a medium.
