An electromagnetic wave is the propagation of electric and magnetic fields through space, carrying energy without the need for a medium. These waves are composed of oscillating electric and magnetic fields that are perpendicular to each other and to the direction of wave propagation. They can travel through a vacuum and encompass a broad range of frequencies, forming the electromagnetic spectrum. Examples of electromagnetic waves include radio waves, microwaves, infrared, visible light, ultraviolet, X-rays, and gamma rays.
