The Electromagnetic Spectrum encompasses all types of electromagnetic radiation, ranging from radio waves to gamma rays. Each type of radiation has a different wavelength and frequency, which determines its properties and uses in various fields such as communication, medicine, and astronomy. Understanding the electromagnetic spectrum is crucial for technologies like radio, microwaves, and X-rays. For instance, visible light is just a small part of this spectrum, allowing us to see the world around us, while other wavelengths can be used for heating food or imaging internal body structures in healthcare.
