Electromagnetic Radiation
Definition of Electromagnetic Radiation as it relates to Science, Physics
Electromagnetic radiation refers to the propagation of energy through space via electromagnetic waves, characterized by oscillating electric and magnetic fields that are perpendicular to each other as well as to the direction of wave propagation. These waves span a wide spectrum, including visible light, radio waves, microwaves, infrared, ultraviolet, X-rays, and gamma rays, each with varying wavelengths and frequencies. Electromagnetic radiation is fundamental to physics and science as it plays a critical role in numerous natural phenomena and technological applications such as communication, imaging, and energy production.
