Electromagnetic radiation (EMR) is a form of energy that travels through space as oscillating electric and magnetic fields, which are perpendicular to each other and to the direction of wave propagation. It moves at the speed of light in a vacuum. EMR spans a broad spectrum that includes gamma rays, X-rays, ultraviolet light, visible light, infrared radiation, microwaves, and radio waves, categorized based on their wavelength or frequency. Visible light is the portion of EMR detectable by the human eye. One of the key features of EMR is its wave-particle duality, where it exhibits properties of both waves and particles called photons. Unlike mechanical waves, EMR does not need a medium to propagate and can travel through the vacuum of space. Its energy is directly proportional to its frequency and inversely proportional to its wavelength. Electromagnetic radiation has a wide range of practical applications in communication technologies, medical diagnostics, remote sensing, and daily appliances such as microwave ovens.
