What is the "electromagnetic spectrum"?
The electromagnetic spectrum is the range of all types of light energy that exist, from the shortest wavelengths like gamma rays to the longest wavelengths like radio waves. It includes visible light, which is the light humans can see, as well as other types like ultraviolet, infrared, and microwave radiation. Each type of light in the spectrum has different properties and uses, from medical imaging to communication technologies.
