The electromagnetic spectrum is a continuum of all electromagnetic waves or radiation, ranging from the shortest gamma rays and X-rays to visible light, ultraviolet, infrared, microwaves, and radio waves with the longest wavelength.
Each type of radiation has distinct properties, uses, and effects on matter.
The electromagnetic spectrum plays a crucial role in various scientific disciplines, including astronomy, telecommunications, and medical imaging. Understanding this spectrum is fundamental for studying the behavior of electromagnetic waves and harnessing their applications in technology and everyday life.
