The electromagnetic spectrum encompasses the entire range of electromagnetic radiation, spanning various wavelengths or frequencies. It includes all forms of electromagnetic waves, each with unique properties and uses. This spectrum is divided into segments based on wavelengths or frequencies, and it includes: Radio Waves: These have the longest wavelengths and are used in broadcasting, communication, and radar technology. Microwaves: With shorter wavelengths than radio waves, microwaves are used in cooking, communication, and satellite transmissions. Infrared Radiation: Beyond microwaves, this includes heat radiation and is used in night vision, remote controls, and thermal imaging. Visible Light: This portion is visible to the human eye and encompasses various colors (ROYGBIV). Ultraviolet Radiation: Beyond visible light, UV radiation is used in medical applications, sterilization, and tanning.
