Electromagnetic Wave

An electromagnetic wave is a type of energy traveling through space that consists of oscillating electric and magnetic fields. These fields are perpendicular to each other and to the direction the wave moves. Electromagnetic waves include visible light, radio waves, X-rays, and more. They don't need a medium to travel, meaning they can move through the vacuum of space. The wave's wavelength and frequency determine its type and properties. Electromagnetic waves carry energy and information, playing a crucial role in communication, medical imaging, and many other technologies.
