The electromagnetic spectrum is the range of all types of electromagnetic radiation, which travels in waves. It includes various forms of energy, categorized by wavelength and frequency. The spectrum spans from very short wavelengths, such as gamma rays and X-rays, to longer wavelengths like ultraviolet light, visible light, infrared radiation, microwaves, and radio waves. Each type of radiation has unique properties and applications. For example, visible light enables us to see, while radio waves are used for communication. Understanding the electromagnetic spectrum is crucial for fields like astronomy, medicine, and telecommunications, as it helps us harness and utilize different types of energy.
