Electromagnetic Radiation
Electromagnetic radiation refers to the energy that travels through space as waves, produced by electrically charged particles. It encompasses a spectrum of waves, including radio waves, microwaves, infrared, visible light, ultraviolet, X-rays, and gamma rays. This radiation is a fundamental aspect of electromagnetism, where electric and magnetic fields interact. In classical electrodynamics, these waves are described by Maxwell's equations, while relativistic electromagnetism accounts for their behavior at high speeds. Electromagnetic radiation is essential in everyday life, enabling technologies like radio, television, and medical imaging.

Electromagnetic radiation is energy that travels through space in waves and includes a spectrum of different types, such as visible light, radio waves, microwaves, infrared, ultraviolet, X-rays, and gamma rays. Each type has a different wavelength and frequency, which determine its properties and uses. For example, visible light allows us to see, while microwaves are used in cooking. This radiation is fundamental to many technologies and natural phenomena, including communication, medical imaging, and the warmth we feel from the sun. It plays a crucial role in our understanding of the universe.
