electromagnetic wave theory
Electromagnetic wave theory describes how electric and magnetic fields interact to produce waves that travel through space. These waves do not require a medium, allowing them to move through a vacuum. Light is a familiar example of such waves, but they also include radio waves, microwaves, and X-rays. The theory, formulated by James Clerk Maxwell, shows that changing electric fields generate magnetic fields and vice versa, creating a self-propagating wave. These waves travel at the speed of light and are fundamental to many technologies, including communication, imaging, and energy transfer.

Electromagnetic Wave Theory describes how light and other forms of radiation, like radio waves and X-rays, travel through space. It combines electricity and magnetism, showing that changing electric fields create magnetic fields and vice versa. This interplay allows energy to propagate as waves, which can travel through a vacuum or air. The theory is essential for understanding various technologies, from radios to lasers, and underpins concepts in physics, such as the behavior of light and the functioning of wireless communication. Ultimately, it reveals the fundamental nature of how energy moves in our universe.
